Request for Comments on Proposed Changes to Restriction Practice in Patent Applications

AGENCY: United States Patent and Trademark Office, Commerce.

ACTION: Request for comments.


1. What should be included in an Office action that sets forth a restriction requirement?

The MPEP currently explains that two criteria must be met to require restriction between patentably distinct inventions, i.e., the inventions must be independent or distinct as claimed, and there must be a serious burden on the examiner if restriction is not required. See MPEP § 803. The Office is considering clarifying the MPEP to indicate that a restriction requirement (including an election of species requirement) must always set forth the reasons why the inventions are independent or distinct and why there would be a serious burden in the absence of a restriction requirement. The Office is considering changes to the burden requirement, an area fundamental to restriction practice. The rationales set forth in the current MPEP to support the burden prong are based on the prior art search (i.e., the inventions have acquired a separate status in the art in view of their different classification; the inventions have acquired a separate status in the art due to their recognized divergent subject matter; and the inventions require a different field of search (for example, searching different classes/subclasses or electronic resources, or employing different search queries)). See MPEP § 808.02. The Office is considering whether to revise the MPEP to indicate that there would be a serious burden if restriction is not required when the prior art applicable to one invention would not likely be applicable to another invention (e.g., because of a different field of art or different effective filing date). The Office is also considering whether to revise the MPEP to specify that ‘‘a serious burden on the examiner’’ encompasses search burden and/or examination burden. Typically, the burden prong has been viewed as referring to the burden imposed by searching for patentably distinct inventions. However, the determination of whether a claimed invention is allowable requires both a search of the prior art and an examination of the application to determine whether the claimed invention meets the statutory requirements for patentability. The burden imposed by the examination of patentably distinct inventions is, in many cases, as serious as the burden imposed by searching for such inventions. Therefore, the Office is considering explaining that in addition to the rationales currently set forth in the MPEP, a serious burden in support of a restriction requirement may be based on the rationale that the inventions are likely to raise different non-prior art issues under 35 U.S.C. 101 and/or 35 U.S.C. 112, first paragraph. In this situation, a serious search burden and/or examination burden may exist where issues relevant to one invention are not relevant to the other invention. The MPEP currently provides for election of species practice when an application includes a generic claim along with separate claims to different species that fall within the scope of that generic claim and that may be patentably distinct. See MPEP § 806.04. The Office is considering revising the MPEP to indicate that in setting forth the species from which an applicant is required to elect, the examiner should group together species that are not patentably distinct from each other, the examiner should require election of either a single species or a single grouping of patentably indistinct species, and the applicant should not be required to elect a specific species within a grouping of patentably indistinct species.


2. What practice changes would result in more effective ways to seek higher level review of restriction requirements?

In various forums, members of the public have expressed overall dissatisfaction with the effectiveness of traversing or requesting reconsideration of requirements for restriction. Unwarranted restriction requirements can result in delays in prosecution, expenditure of excess claim fees, and/or the need to file multiple divisional applications to avoid dedication of unclaimed subject matter to the public. The Office invites suggestions from the public as to how to improve the traversal or request for reconsideration process within the framework of the current rules (see 37 CFR 1.143 and 1.144) to achieve more consistent, accurate, timely, and cost-effective review.


3. How could the Office clarify requirements for restriction between related product inventions or related process inventions where the relationship is not specifically provided for in MPEP Chapter 800?

The Office is considering providing for a new section in the MPEP to address restriction between related product inventions or related process inventions not otherwise provided for in MPEP §§ 806 through 806.05(j). See, e.g., MPEP § 806.04 et seq. for restricting between inventions in a genus/species relationship; MPEP § 806.05(c) for an explanation of the requirements to restrict between inventions in a combination/ subcombination relationship; MPEP § 806.05(d) for restricting between subcombinations disclosed as usable together; and MPEP § 806.05(j) for restricting between an intermediate and a final product. Specifically, the Office is considering explaining that to support a requirement for restriction between two or more related product inventions, or between two or more related process inventions, that are not otherwise provided for in MPEP §§ 806 through 806.05(j), there must be two-way distinctness (see MPEP § 802.01) and a serious burden if restriction were not required. The Office is considering explaining that for such related product inventions or such related process inventions, the inventions are distinct if: (1) The inventions as claimed have mutually exclusive characteristics (see MPEP §§ 806 through 806.05(f)); (2) the inventions as claimed are not obvious variants over each other; and (3) each invention as claimed can be made by, or used in, a materially different process or product. In an effort to reduce the number of improper requirements for restriction between related product inventions or related process inventions, the Office is considering explaining that where claims of an application define the same essential characteristics of a single invention, e.g., the claims vary from each other only in breadth or scope (ranging from broad to detailed), the examiner should not require restriction between such claims.


4. How could the Office modify Markush practice?

The Office is considering whether to revise Markush practice in three particular ways. First, if the examiner determines that the elected species is allowable, the Office is considering specifying that the examination of the Markush-type claim will be extended to the extent necessary to determine the patentability of the claim, i.e., to determine whether any nonelected species is unpatentable for any reason (35 U.S.C. 101, 102, 103, or 112, or nonstatutory double patenting). If a nonelected species is determined to be unpatentable, the Markush-type claim would be rejected, and the search and examination would not be extended to cover all nonelected species. Next, the Office is considering revising the treatment of amended Markush-type claims to clarify that whether an Office action may be made final is determined by whether the conditions in MPEP § 706.07 for making a second or subsequent Office action final are met and is not dependent upon whether the examiner previously required a provisional election of species. Lastly, the Office is considering situations where restriction may be proper between a subcombination and a combination when a subcombination sets forth a Markush grouping of alternatives. In particular, the Office is referring to a subcombination that (1) encompasses two or more subcombination embodiments within its scope, and (2) lists those embodiments using Markush-type claim language, i.e., lists the embodiments as a group of alternatives from which a subcombination embodiment is selected. For example, the Office is considering whether restriction would be proper between a subcombination claim to an individual DNA molecule selected from a list of alternative embodiments and a combination claim to an array comprising a plurality of DNA molecules wherein one or more of the DNA molecules are selected from the list of alternative embodiments set forth in the subcombination claim. In such a situation, the combination claim does not require all the elements of any particular claimed subcombination to be present in the claimed array. Apart from these specific considerations, the Office invites suggestions from the public regarding changes to the practice of requiring election/restriction of Markush claims in a manner that balances the interests of the Office and those of the public in the context of the current statutory and regulatory framework.


5. How could the Office improve rejoinder practice?

The Office is considering changes to rejoinder practice as part of an effort to institute more uniform treatment of claims directed to nonelected subject matter upon the determination that all claims to the elected invention are allowable. The Office is considering whether to define ‘‘rejoinder’’ as the practice of withdrawing a restriction requirement as between some or all groupings of claims and reinstating certain claims previously withdrawn from consideration that occurs when the following conditions are met: (1) All claims to the elected invention are allowable; and (2) it is readily apparent that all claims to one or more nonelected inventions are allowable for the same reasons that the elected claims are allowable. Claims that meet the second condition for rejoinder may include, for example, those that (1) properly depend from an allowable elected claim; (2) include all of the limitations of an allowable elected claim; or (3) require no further search and/or examination. Claims that may not be eligible for rejoinder would include, for example, those that require additional consideration of the prior art or raise utility, enablement, or written description issues not considered during examination of the allowable elected claims. Separately, the Office is also considering instructing examiners that when all claims directed to an elected invention are allowable, nonelected claims must be considered for rejoinder and withdrawal of the restriction requirement. In making this decision, examiners must reevaluate both aspects of the restriction requirement, i.e., whether the nonelected invention(s) as now claimed are independent or distinct from the claim(s) to the allowable elected invention and whether there would be a serious burden if the nonelected inventions were rejoined.


6. What other areas of restriction practice can the Office improve and how?

While the Office has set forth particular restriction practice issues for which comments are specifically being requested, the Office is in this request for comments inviting comments on any area in which restriction practice could be improved.
