    As Patent Docs
    reported on Wednesday, Patent Commissioner John Doll (at right) was the luncheon speaker at
    the American Conference Institute’s Biotech Patents conference in Boston.  During the question-and-answer session, the Commissioner
    was asked about information one participant had received from a Patent Office
    official regarding divisional application practice.  Specifically, the question was about the
    effect of filing a Chapter II Demand and receiving an International Preliminary
    Examination in a PCT application claiming priority to a provisional application
    that had also been converted to a U.S. non-provisional application.  In the scenario, the U.S. Examiner imposes a
    restriction requirement in the non-provisional application, and the question
    was whether the applicant had a right to file a divisional application on the
    non-elected Wipo
    claims.  The Patent Office
    official had told the questioner that the Office would consider a divisional to
    be precluded for any claims examined during the International phase, since the
    new rules limited divisional application claims to claims that had not been
    previously examined.  According to the
    official, the International Preliminary Examination would qualify as a
    "previous examination," and the divisional filing would be improper.

    Uspto_seal
    Commissioner
    Doll stated at lunch that it was not the Office’s intention that an International
    Preliminary Examination would preclude an applicant from filing divisional
    applications in response to a U.S. Examiner-imposed restriction requirement in
    a national phase application.  He also
    promised to "get back to us" on the proper interpretation of the
    rule.

    It seems
    that overnight Commissioner Doll either had a change of heart or was informed
    that he was misinformed.  To clarify, if
    a PCT application undergoes International Preliminary Examination, the Patent
    Office will count that as a "previously-examined claim" and preclude
    an applicant from filing a divisional application on any such claim in response
    to a restriction requirement.  This
    interpretation can be found in Frequently Asked Qustions (FAQ) Nos. C8 and C11
    on the Patent Office website:

    C8.  If applicant filed an initial application which is an
    international application designating the U.S. and the international
    application contains two inventions, can applicant file one continuation
    application and submit a suggested restriction requirement (SRR) in the
    continuation application rather than file two continuation applications?  Will
    the Office count the withdrawn claims in determining whether the continuation
    application exceeds the 5/25 claim threshold?  (Posted on 9/26/07)

    Yes, an applicant may file a continuation application and
    submit an SRR in the continuation application in lieu of filing two separate
    continuation applications.  If the SRR is accepted and the examiner makes a
    restriction requirement, applicant may file a divisional application for the
    claims to the non-elected invention that has not been examined.  Note that
    applicant may not file a divisional application to claim an invention that has
    been examined in the international application designating the U.S. upon the
    filing of a Demand.

    The Office will not count the withdrawn claims in
    determining whether an application exceeds the 5/25 claim threshold.  Therefore,
    if the elected invention in the continuation application is drawn to 5/25 or
    fewer claims, applicant is not required to file an ESD before the FAOM.

    C11.  If applicant filed an initial application which is
    an international application designating the U.S. and the International
    Searching Authority determined that the international application lacks unity
    of invention under PCT Rule 13, can the applicant file a divisional application
    for the non-elected invention that was not examined in the international
    application?  (Posted on 9/26/07)

    Yes, applicant may file a divisional application for each
    non-elected invention that was not examined in the international application.  However, if applicant filed a Demand and paid the additional examination fees
    and all of the inventions were examined in the international application,
    applicant may not file a divisional application.  This is because under PCT
    Article 31, "examination" in the international phase is contingent
    upon the filing of a Demand for international preliminary examination.  The
    non-elected invention would be examined within the meaning of 37 CFR
    1.78(d)(1)(ii) in the international application designating the U.S.

    Thus, it is
    now foolhardy to file a Chapter II Demand in any PCT application claiming
    priority to the U.S.  In view of the
    differences, long touted by the Patent Office and recognized in voluminous case
    law, between the standards of an International Preliminary Examination and a
    U.S. Patent Office examination, this interpretation exceeds the ironic and
    borders on the nonsensical (and probably is contrary to U.S. law), but that
    doesn’t seem to be a factor in the Office’s decision-making.

  • Eli Lilly & Co. v. Emisphere Techs., Inc., No.
    03-cv-1504-DFH (S.D. Ind.)

        By Robert Dailey

    Lilly
    This week Eli Lilly agreed to pay $18 million to settle
    its contract and patent dispute with biotech start-up Emisphere.  In the late 90s, the two companies had agreed
    to work together to develop an oral delivery of parathyroid hormone (PTH) for
    treatment of osteoporosis.  Lilly already
    sells Forteo®, an injectable delivery of recombinant human PTH 1-34.  But Lilly, like many drugmakers, preferred to
    market an oral delivery.

    Logo_2

    Emisphere is a small biotech company in upstate New York
    that specializes in drug delivery technologies.  Particularly, Emisphere develops proprietary carrier molecules that
    enable therapeutic proteins to bypass the digestive process and pass through
    the intestinal wall into the bloodstream.  Ordinarily, digestive processes would metabolize any peptide-based
    therapies, rendering them unavailable as a drug.  Lilly sought to use Emisphere’s technology to
    develop an oral delivery for PTH, a small peptide.

    The relationship went smoothly for six years as both
    companies shared proprietary information.  As part of the contract between the companies, Lilly agreed not to
    conduct research on Emisphere’s carrier technology for projects other than the
    development of an oral delivery for PTH and human growth hormone.  The contract also placed limits on Lilly’s
    internal distribution of knowledge related to Emisphere’s technology.  The parties further agreed that Emisphere
    would own any inventions arising out of the collaboration.  For Lilly, the prospect of cashing in on an
    oral delivery of PTH outweighed the burdensome provisions of the joint research
    agreement.

    But the relationship soured in September 2003 when
    Emisphere identified a published Lilly PCT application (International Pub. No. WO 03/072195)
    which it believed covered the use of its carrier technology for the delivery of glucagon-like
    peptide (GLP), a protein outside of the scope of the collaboration.  Emisphere terminated the
    contract, and Lilly filed a declaratory judgment action contesting Emisphere’s
    right to terminate.

    Insd_seal2
    In a 2005 bench trial, a District Court in Indianapolis
    found that Lilly had breached its agreement with Emisphere by (1) using the carrier technology for projects that lay outside of the
    agreed scope of the collaboration, and (2) disseminating proprietary knowledge
    of Emisphere’s technology to unapproved researchers at Lilly.  Therefore, the District Court permitted
    Emisphere to terminate its relationship with Lilly, and issued an injunction
    ordering Lilly to assign all of its interest in the inventions of WO 03/072195
    to Emisphere.  Lilly indicated that it
    would appeal Judge Hamilton’s injunction, but PACER records for the Seventh
    Circuit show no indication of an appeal having been filed.

    Additionally, Emisphere sought to recover monetary
    damages for Lilly’s contract breach, and sought to hold Lilly liable for patent
    infringement.  For the past 18 months,
    the two parties have been conducting discovery related to these issues.  The settlement is unsurprising, though, since
    Judge Hamilton’s previously issued opinion
    and order
    are not favorable for Lilly.

    The terms of the agreement are confidential.  The $18 million is a substantial sum for a
    company of Emisphere’s size.  That sum
    represents its entire research budget for 2006, and is nearly triple the amount
    that Emisphere earned from its collaborations in 2006.  The Lilly-Emisphere PTH project appears to be
    dead; Emisphere is now working with Novartis to develop an oral delivery of PTH
    1-34.  Press reports have not disclosed
    whether Emisphere granted Lilly a license to keep using the carrier technology
    that Lilly had learned from the six-year collaboration.  Emisphere’s stock price moved about 5-10%
    following this announcement.

  •     By Donald Zuhn

    Last Friday, the Federal Circuit reversed a District Court’s finding on summary judgment that eight generic drug manufacturers did not infringe U.S. Patent No. 6,054,482 (the ‘482 patent), and affirmed the District Court’s construction of two disputed claim limitations.

    Pfizer
    Plaintiffs-Appellants Warner Lambert Co., Pfizer Inc., and Gödecke Aktiengesellschaft (Warner Lambert) manufacture and sell Neurontin®, which is used to treat cerebral disorders such as epilepsy and which comprises the active ingredient gabapentin.  Warner Lambert discovered that under certain manufacturing conditions, gabapentin can form a lactam.  To minimize the formation of the lactam, which is twenty-five times more toxic than gabapentin and which causes – rather than prevents – seizures, Warner Lambert developed a process for preparing stable and safe gabapentin formulations.  The ‘482 patent is directed towards this process as well as to gabapentin compositions that are substantially free from a lactam contaminant.

    Teva_1
    Seeking approval to market generic gabapentin, Defendants-Appellees Purepac Pharmaceutical Co., Faulding Inc., Teva Pharmaceutical Industries, Inc., Teva Pharmaceuticals USA, Inc., Zenith Laboratories, Inc. (now IVAX Pharmaceuticals NV, Inc.), Zenith Goldline Pharmaceuticals, Inc. (now IVAX Pharmaceuticals, Inc), IVAX Corp., and Eon Labs Manufacturing, Inc. (Appellees) filed Abbreviated New Ivax
    Drug Applications (ANDAs) with the FDA.  In response, Warner Lambert brought number of infringement actions against the Appellees; the suits were consolidated in the District Court of New Jersey.

    In pretrial proceedings, the Appellees moved for summary judgment of noninfringement and invalidity of the ‘482 patent.  The District Court granted Appellees’ motion for summary judgment of noninfringement, determining that Warner Lambert had failed to establish that the accused products contained no more than 20 parts per million (ppm) of anions of mineral acid as required by the asserted claims (more anions of mineral acid indicates the presence of gabapentin hydrochloride – the salt form of gabapentin, which in turn indicates that the gabapentin sample is less pure, and therefore, less stable; less stable formulations of gabapentin contain lactam contaminant).  In addition, the District Court construed two claim terms in Warner Lambert’s favor.  In particular, the District Court construed the term "anion of a mineral acid" as an "anion derived from a mineral acid" and the term "adjuvant" as a "subset of [eight particular] inactive ingredients that is intimately mixed with gabapentin to form the drug mixture, and thus [does not] refer to the ingredients of capsule shells or tablet coatings."

    On appeal, Warner Lambert argued that the District Court, in granting summary judgment of noninfringement, erred by resolving factual disputes.  In opposing the Appellees’ motion for summary judgment, Warner Lambert had submitted the results of a comparative pH test that established that four of five of the Appellees’ samples tested contained not more than 17 ppm of anions of mineral acid.  In response, the Appellees challenged the accuracy and reliability of Warner Lambert’s comparative pH test.

    The Federal Circuit, however, noted that the Appellees had "waived any argument challenging the validity, including challenges to the accuracy or reliability, of the pH testing method for purposes of summary judgment," and were therefore confined to arguing against "the undisputed limits of the test’s precision" (i.e., a ± 5 ppm margin of error).  When so confined, the CAFC concluded that the Appellees could not counter Warner Lambert’s demonstration that the Appellees’ gabapentin (at left) samples contained less than 20 ppm of anions of a mineral acid, as recited in the claims.  Thus, the Federal Circuit concluded that "the district court erred in granting summary judgment of noninfringement based on Warner Lambert’s purported failure to meet its burden of proof" since "[t]he record shows that Warner Lambert proffered sufficient evidence to create a genuine issue of material fact regarding whether the accused products met the 20 ppm claim limitation of the ‘482 patent."

    With respect to the District Court’s construction of the term "anion of a mineral acid," the Appellees argued that the term refers to total chloride content and is not limited to acid-derived chloride ions. The Appellees also argued that the term "adjuvant" refers to any ingredient other than the active ingredient, and thus encompasses ingredients included in the capsule shell or tablet coating.

    In affirming the District Court’s construction of the first disputed claim term, the Federal Circuit determined that "the construction adopted by the district court gives full meaning to every word of the entire claim term," and that "[h]ad the patentees intended the anion to refer to any anion, regardless of its source, the patentees could have simply claimed ‘anions’ and omitted the phrase ‘of a mineral acid.’"  With respect to the second disputed claim term, the CAFC noted that the District Court had "found nothing in the patent or prosecution history indicating that ingredients found in the capsule shell or coating affects stability, and also relied on several dictionary definitions in support of its construction."  As a result, the Federal Circuit concluded that the District Court also did not err in construing the term "adjuvant."

    Novartis
    Late last week, Novartis and Ranbaxy filed a joint stipulation and dismissal in their pending lawsuit over generic valsartan, the active ingredient in Novartis’ Diovan®, used to treat hypertension.  The suit, filed on August 9, 2007 in the District Court of New Jersey (see previous report), had been pending only 5 weeks when Ranbaxy amended its ANDA filing, converting its Paragraph IV certification to a Paragraph III certification.  One week later the parties filed their stipulation and dismissal.

    Ranbaxy
    As noted in the stipulation, the amendment to a Paragraph III certification means that Ranbaxy agrees not to make, use, sell, offer to sell, or import into the United States any product until after the expiration of Novartis’ exclusivity, or until the claims of the patent-in-suit are declared invalid or unenforceable following a final decision in a U.S. district court.  The patent in suit is U.S. Patent No. 5,399,578 ("Acyl Compounds," issued March 21, 1995).  Novartis’ exclusivity terminates on September 21, 2012 based on a 6-month Pediatric Exclusivity granted beyond the expiration date of the ‘578 patent.

    Doll_john
    The American Conference Institute is holding its Biotech Patents conference this week in Boston, and the lunchtime speaker was John Doll, Commissioner for Patents.  Commissioner Doll (at right) is the happy face of the U.S. Patent and Trademark Office:  smiling, self-deprecating, and charming while he espouses the Patent Office mantra that the Office is willing to do everything possible to improve the patenting process in the United States.  And if his audience was skeptical, it was due in part to opposition to the recently-issued final rules for patent continuations and limitations on the number of claims.  Another factor is that Commissioner Doll’s numbers in support of his message don’t add up (like they didn’t in the infamous Town Hall meetings that accompanied the new rules when first proposed).

    Uspto_seal_no_background
    The Commissioner provided historical and recent evidence on patent "quality," which he explained was determined by reviewing applications allowed by the Examining Corps, and rejecting any application having at least one claim that "should not have been allowed."  The data show that this "allowance error rate" has ranged between 7.5% and 2.75% over the past thirty-two years, and is at about 3.5% for 2006 (the last year for which the statistics are available).  The Commissioner did not explain whether the "errors" calculated in this way were based on art, sufficiency of disclosure (i.e., under 35 U.S.C. § 112) or other sections of the rules or statutes (such as obviousness-type double patenting).  Also not addressed was the converse error rate:  the number of pending applications having at least one patentable claim the Office refuses to allow; he did indicate that this kind of review was done and had a conclusory slide claiming a 90% "in process compliance rate" for this metric (i.e., about 3-fold higher than the allowance error rate; the Office is obviously content when claims that should be allowed are not).  In view of the complexity of the issues that can be presented during patent prosecution, and the amount of time it takes for an examiner to properly understand the invention and its relationship to the art, it is likely that the "error rate" with which the Patent Office "allowance error rate" is determined is both high and the result of cursory and subjective determinations.

    Also provided were statistics relating to the patent allowance rate (which the Commissioner explained was determined by dividing the number of allowed patents by the total of allowed patents, abandoned patents, and patents for which there was prepared an Examiner’s Answer on appeal, at which point the application was considered "disposed" to the Board of Patent Appeals and Interferences).  This rate has varied over the same 32-year time period from a high of a little more than 70% to the current low of less than 50%, and the Commissioner predicted that rate could be expected to further decrease in view of the new examination guidelines for applying the Supreme Court’s KSR decision.  (The post-KSR obviousness guidelines are supposed to be published in the Federal Register and posted on the Patent Office website some time in the next two weeks.)  Commissioner Doll overlayed the two graphs to show the error rate and allowance rates tended to trend together; however, the reduction in patent allowance rate cannot be explained by the decrease in the allowance error rate.  And the Commissioner had no explanation for the decrease in allowance rate over the past five years.

    The Commissioner repeated the Patent Office statistics that the backlog of unexamined cases is growing and that patent examiner hiring could not overcome the increase.  (The census of the Patent Examining Corps stood at 5,150 examiners at the end of fiscal year 2006; although the hiring goal for FY2007 is 1,200 new examiners, only 127 have been hired to date and the Office has experienced attrition of 430 examiners.)  He also admitted that there are no longer sufficient numbers of supervisory patent examiners or primary examiners to train the new examiners, necessitating the "patent academy approach."  Thus, rather than being the result of a reasoned decision in favor of the academy approach, it appears that examiners are being trained this way out of necessity.  (The Commissioner also admitted that there were several examiners who "should be returned to the private sector" but refused to identify them.)  Pendency in the biotechnology art unit is at about 23 months to first action and 35 months overall.

    Efsweb
    The Commissioner is appropriately proud of the electronic filing system, which is now used to file more than 60% of the applications filed each week.  He also extolled the virtues of the Accelerated Examination (AE) program (which replaced the Petition to Make Special practice) and the pilot peer review program.  The AE program has been used by only a small number of applicants, in part because the Office set a significant number of hurdles for an application to qualify.  However, the Commissioner reported that one application in Technology Center 2800 issued within 97 days (and was allowed in 18 days).  Examiners in the program are reviewing unpublished applications (since these will qualify as prior art unavailable during the truncated prosecution of the AE program), and in instances where relevant unpublished patents are found, the application is withdrawn from the program and prosecution suspended until the application becomes available.

    Map_2

    Regarding the peer review pilot program, which is being run for the Office by New York Law School, 35 applications have volunteered for the program and 18 applications posed on the peer review website (www.peertopatent.org).  Only applications in Technology Center 2100 (Computer Architecture Software and Information Security) are currently eligible for the program, although the Commissioner opined that biotechnology applications were a likely candidate for expanding the program once it has been evaluated after a one-year pilot period.  Commissioner Doll explained that the program would send an examiner up to ten prior art references submitted in the program, including any comments or annotations submitted with the art.  (It is ironic that the Office has typically given scant notice to determinations of prior art relevance from foreign patent offices, as evidenced for example in an International Search Report received in PCT applications, and is now providing examiners with the comments submitted by the public with these references.  As mentioned by the luncheon audience, the likelihood that a competitor will try to manipulate the system against an applicant is high, and the Office appears to be uninterested in the consequences of this possibility.)

    The Commissioner "had a plane to catch" and so was unavailable to discuss the new continuation and claims rules.  However, he did acknowledge that some Patent Office personnel were providing incorrect information in response to inquiries; for example, he said it was not the Office’s intention that an International Preliminary Examination would preclude an applicant from filing divisional applications in response to a U.S. Examiner-imposed restriction requirement in a national phase application, but that the rules seemed to so indicate and some Office personnel were misinterpreting the rules in this way.

    The continuing message was patent quality, but with a hint (as has been the case throughout) that the blame for any lack of quality lies with applicants and their attorneys.  He sweetened this message by inviting everyone (applicants, attorneys, and the public) to participate in the Patent Public Advisory Committee Outreach program which will occur over the next several months (although the Office’s performance in the continuation/claims rules does not inspire confidence).

    Finally, Commissioner Doll invited anyone who has the experience that an examiner is not applying the rules properly, or is "churning" an application by reiterating rejections or not explaining why an applicant’s response is insufficient, or by citing additional art and/or rejections after an applicant has addressed and overcome previously-asserted grounds of rejection, should contact him directly so he can apply what he called some "one-on-one" training.  Although perhaps sincere, it is also naïve to think that an applicant would avail themselves of this opportunity, since it is almost certain to eliminate the possibility that the examiner would ever deign to allow an application submitted for examination by that applicant.  And the hollowness of the offer did little to dispel the impression that Commissioner Doll’s road show is intended more for appearance than substance and is largely irrelevant to the task of understanding the consequences of the violent changes his administration is making to the patent application process.

    As previously reported on Patent Docs, the biotechnology and chemical pharmaceuticals technology groups at the U.S. Patent Office held their most recent quarterly customer partnership meeting on September 12, 2007.  While we were unable to attend the webcast on the day of the meeting, we will summarize a couple of the presentations (available at http://www.cabic.com/bcp) based on the archived slideshows.

    One presentation focused on restriction requirement practice as applied to inventions claiming nucleic acid molecules.  Julie E. Burke, QAS/PM, from Technology Center 1600 presented the slideshow (available here), which provided some background on how restriction practice relating to nucleic acids has evolved, basic restriction guidelines and tests for distinctness of invention/species and examples of proper restriction practice in seven common types of claims relating to nucleic acid technology, and in which of those types of claims Applicants will be restricted to a single sequence in an application.  These seven examples include inventions where: (1) different sequence identifiers (SEQ ID NOs) describe a single invention; (2) when sequences fully overlap; (3) practice for a combination claim; (4) distinct nucleic acid molecules; (5) a single sequence identifier may encompass two or more species; (6) a claim that depends upon, but does not link plural distinct inventions; and (7) a dependent claim that cannot be restricted from its independent and intervening claim(s).


    1st Example:

    1.  An isolated nucleic acid comprising SEQ ID NO: 1.
    2.  An isolated nucleic acid encoding a protein having SEQ ID NO: 2.

    — The specification discloses a nucleic acid comprising SEQ ID NO: 1 which contains the open reading frame for a protein having SEQ ID NO: 2.
    — Claims 1 and 2 are not distinct from each other because the claims merely define the nucleic acid using different limitations.

    Restriction between Claims 1 and 2 is NOT APPROPRIATE.


    2nd Example:

    1.  An isolated nucleic acid molecule comprising SEQ ID NO: 1.
    2.  An isolated nucleic acid molecule comprising SEQ ID NO: 2.
    3.  An isolated nucleic acid molecule comprising SEQ ID NO: 3.

    — The term "comprising" permits additional nucleic acids at either end of the sequence.
    — The sequence listing shows that SEQ ID NOs: 1, 2, and 3 fully overlap with each other.
    — Assume that the sequences are:

    SEQ ID NO: 1 = ATGTGCGATA
    SEQ ID NO: 2 = ATGTGCGATA ATCTG
    SEQ ID NO: 3 = ATGTGCGATA ATCTGTTATA

    — The nucleic acid molecules comprising SEQ ID NO: 1, 2, and 3 are not distinct from each other, as claimed.
    — As a practice tip, the PTO suggests using this claim format to refer to a single sequence in order to highlight the common region and avoid improper restriction:

    1.  An isolated nucleic acid molecule comprising residues 1-10 of SEQ ID NO: 3.
    2.  An isolated nucleic acid molecule comprising residues 1-15 of SEQ ID NO: 3.
    3.  An isolated nucleic acid molecule comprising SEQ ID NO: 3.

    Restriction to a single sequence of SEQ ID NOs: 1, 2, and 3 is NOT APPROPRIATE.


    3rd Example:

    1.  A kit comprising primers having SEQ ID NO: 1-100.

    — The presence of one novel and nonobvious sequence within the combination will render the entire combination allowable.
    — The combination will be searched until one nucleotide sequence is found to be allowable.
    — The order of searching will be chosen by the examiner to maximize the identification of an allowable sequence.
    — If no individual nucleotide sequence is found to be allowable, the examiner will consider whether the combination of sequences taken as a whole renders the claim allowable.

    In general restriction of a combination of nucleotide molecules is NOT APPROPRIATE.


    4th Example:

    1.  An isolated nucleic acid comprising SEQ ID NO: 1.
    2.  An isolated nucleic acid comprising SEQ ID NO: 2.

    — The specification teaches that SEQ ID NO: 1 encodes a ribosomal protein and SEQ ID NO: 2 encodes an enzyme.
    — Thus, claims 1 and 2 are distinct from each other because the mutually exclusive characteristic of SEQ ID NO: 1 is not encompassed by claim 2, and the mutually exclusive characteristic of SEQ ID NO: 2 is not encompassed by claim 1.
    — Examination of Claim 1 and 2 would be burdensome because (a) each sequence requires a different search query, and (b) prior art for one sequence is not likely to teach the other sequence.

    Restriction between the nucleic acid molecules comprising SEQ ID NO: 1 and SEQ ID NO: 2 is APPROPRIATE.


    5th Example:

    1.  An isolated nucleic acid consisting of SEQ ID NO: 1.

    — Claim 1 refers to a single sequence identifier and uses closed transitional language "consisting of."
    — The phrase "consisting of" followed by a single sequence identifier generally limits a claim to a single fully defined nucleic acid molecule.
    — The sequence listing shows that SEQ ID NO: 1 is ATGSTAMATR, where S is G or C, M is A or C, and R is G or A.
    — Therefore SEQ ID NO: 1 actually encompasses eight patentably distinct sequences:

    ATGGTAAATG
    ATGGTAAATA
    ATGCTAAATG
    ATGCTAAATA
    ATGGTACATG
    ATGGTACATA
    ATGCTACATG
    ATGCTACATA

    Restriction in this situation can include an election of species because generic claim 1 reads upon all eight disclosed species.


    6th Example:

    1.  An isolated nucleic acid having SEQ ID NO: 1.
    2.  An isolated nucleic acid having SEQ ID NO: 2.
    3.  A vector comprising the nucleic acid of claim 1 or claim 2.
    4.  A host cell comprising the vector of claim 3.

    — SEQ ID NO: 1 and SEQ ID NO: 2 are distinct from each other as in the 4th Example (ribosomal protein and enzyme, respectively).
    — A linking claim must be broader in scope than the linked claims.  Thus, claims 3 and 4 are NOT linking claims because claims 3 and 4 are narrower in scope that claims 1 and 2.
    — The claims may be grouped as follows:

    • Group I:  claim 1 and claims 3 and 4, in part, drawn to nucleic acid, vector, and host cell having SEQ ID NO: 1.
    • Group II:  claim 2 and claims 3 and 4, in part, drawn to nucleic acid, vector and host cell having SEQ ID NO: 2.

    Restriction between the two Groups is APPROPRIATE.


    7th Example:

    1.  An isolated nucleic acid comprising SEQ ID NO: 1.
    2.  An isolated nucleic acid of claim 1, further comprising SEQ ID NO: 2 added to the 3′ end.
    3.  An isolated nucleic acid of claim 2, further comprising SEQ ID NO: 3 added to the 3′ end.

    — Alignment of the sequences shows that SEQ ID NOs: 1, 2, and 3 are distinct from each other:

    SEQ ID NO: 1 = ATGTGCGATA
    SEQ ID NO: 2 = TGGTACATGC
    SEQ ID NO: 3 = ATTTAGCTATT

    — Claims 1, 2, and 3 are not distinct from each other, because the claims could be alternatively presented as:

    1.  A nucleic acid comprising ATGTGCGATA.
    2.  A nucleic acid comprising ATGTGCGATA TGGTACATGC.
    3.  A nucleic acid comprising ATGTGCGATA TGGTACATGC ATTTAGCTATT.

    — A dependent claim must incorporate all the limitations of the independent and any intervening claims.

    Restriction between the nucleic acids of claims 1, 2, and 3 is NOT APPROPRIATE.


    Conclusion:

    While many of the issues and questions surrounding restriction practice under the New Rules regarding Claims and Continuing Application Practice will not be answered or come to light until after November 1, 2007, this presentation at least provides some guidance to Applicants with inventions that relate to nucleic acid molecules.  This guidance allows for some degree of prospective planning in application and claim drafting strategies.
