When restriction is proper

When restriction is proper

Authority for restriction • The authority for requiring a restriction between inventions is based

Authority for restriction • The authority for requiring a restriction between inventions is based in 35 U. S. C. 121 divisional applications, which reads in part: If two or more independent and distinct inventions are claimed in one application, the Director may require the application to be restricted to one of the inventions. • Restriction is the practice of requiring an applicant to elect a single, claimed invention for examination when two or more independent inventions and/or two or more distinct inventions are claimed in the application. – The terms “independent” (i. e. , unrelated) and “distinct” (i. e. , related but patentably distinct) have mutually exclusive meanings and thus are interpreted as alternative requirements. Only one of these requirements must be met in order to support a restriction. MPEP 802, 802. 02 May 2019 Restriction Practice 4

When restriction is proper • For a proper requirement for restriction between patentably distinct

When restriction is proper • For a proper requirement for restriction between patentably distinct inventions, there are two criteria: (i) Showing the inventions are independent or distinct as claimed AND (ii) Showing that there would be a serious search and examination burden on the examiner if restriction is not required. • A restriction requirement is made at the discretion of the examiner. – Restriction is NOT a tool for reducing the number of claims for mere convenience. MPEP 803(I) May 2019 Restriction Practice 5

Independent inventions • Inventions, as claimed, are independent (i. e. , unrelated) if there

Independent inventions • Inventions, as claimed, are independent (i. e. , unrelated) if there is no disclosed relationship between the inventions. That is, they are unconnected in design, operation, and effect. • For example: versus MPEP 802. 01 I, 806. 06 May 2019 Restriction Practice 6

Independent inventions (cont. ) • Restriction to one independent invention can be required when:

Independent inventions (cont. ) • Restriction to one independent invention can be required when: – It can be shown that two or more inventions are independent, and – There would be a serious burden on the examiner if restriction is not required. • Examples include: Two different combinations, not disclosed as capable of use together, having different modes of operation, different functions, and different effects: o An article of apparel and a locomotive; a process of painting a house and a process of boring a well. Where the two inventions are process and product, and the product cannot be used in, or made by, the process: o A specific process of molding is independent from a molding apparatus that cannot be used to practice the specific process. • Use FP 8. 20. 02 to restrict between independent, unrelated inventions and FP 8. 20. 03 to restrict between an unrelated product and process. MPEP 806. 06 May 2019 Restriction Practice 7

Related but distinct inventions These cash registers are related, but may be considered distinct

Related but distinct inventions These cash registers are related, but may be considered distinct if found to be not connected in at least one of design, operation, or effect. versus MPEP 802. 01 II, 803 May 2019 Restriction Practice 8

Related but distinct inventions (cont. ) • Two or more inventions are related (i.

Related but distinct inventions (cont. ) • Two or more inventions are related (i. e. , not independent) if they are disclosed as connected in at least one of design (e. g. , structure or method of manufacture), operation (e. g. , function or method of use), or effect. Related inventions are distinct if the inventions as claimed are not connected in at least one of design, operation, or effect (e. g. , can be made by, or used in, a materially different process) and wherein at least one invention is PATENTABLE (novel and nonobvious) OVER THE OTHER (though they may each be unpatentable over the prior art). • Restriction can be required when related inventions can be shown to be distinct and there would be a serious burden on the examiner if restriction is not required. MPEP 802. 01 II and 806. 05 May 2019 Restriction Practice 9

Showing serious burden • Reasons must be provided as to why a serious search

Showing serious burden • Reasons must be provided as to why a serious search and examination burden would exist if restriction was not required. • Serious burden can be shown if the inventions have one or more of the following: a) Separate classification. - To show that each invention has attained recognition in the art as a separate subject for inventive effort, and also a separate field of search (patents need not be cited). b) Separate status in the art when they are classifiable together. - To show a recognition of separate inventive effort by inventors, may be shown by citing patents which are evidence of such separate status, and also of a separate field of search. c) A different field of search. - To show it is necessary to search for one of the inventions in a manner that is not likely to result in finding art pertinent to the other invention(s) (e. g. , searching different main groups/sub-groups or electronic resources, or employing different search queries), even though the inventions are classified together (patents need not be cited). MPEP 803 II, 803. 02, 806. 05, 808. 02; FP 8. 21 May 2019 Restriction Practice 10

When restriction is not appropriate Restriction cannot be required when one or more of

When restriction is not appropriate Restriction cannot be required when one or more of the following are true: • No serious burden exists in searching and examining the claims, even if the claims are drawn to independent or distinct inventions; • Inventions are not distinct as claimed; • There is an express admission that the claimed inventions would have been obvious over each other within the meaning of 35 U. S. C. 103; or • Claims define the same essential characteristics of a single disclosed embodiment. MPEP 803, 806. 03 May 2019 Restriction Practice 11

Restriction and non-statutory double patenting If the examiner indicates, via restriction, that inventions A and B are independent or patentably distinct, this would prohibit any later assertion that A and B are patentably indistinct under non-statutory double patenting, except as noted below (and in MPEP 804. 01). • A nonstatutory double patenting rejection between separate applications to A and B could be properly made if the restriction requirement was withdrawn before the rejection. • A nonstatutory double patenting rejection between separate applications to A and B could be properly made if the examiner later determines that the inventions are patentably indistinct and the later application is not a divisional application that has consonance with the restriction requirement. Consonance means maintaining the line of demarcation between the independent and distinct inventions identified in the restriction requirement. MPEP 804. 01 B MPEP 804. 01 A-H May 2019 Restriction Practice 13

Restriction and non-statutory double patenting (cont. ) • When restriction is required, the examiner

Restriction and non-statutory double patenting (cont. ) • When restriction is required, the examiner is prohibited from making a nonstatutory double patenting rejection against any claim in a subsequent divisional application that is directed only to any of the originally non-elected inventions under 35 U. S. C. 121, unless the restriction requirement was withdrawn. • Improperly applying restriction to patentably indistinct sets of claims can result in the possibility of multiple patents being awarded for patentably indistinct variations of the same invention, since non-statutory double patenting against the divisional applications is prohibited. – Multiple patents for the same invention could lead to multiple lawsuits against an accused infringer by different assignees of patents to the indistinct claims. MPEP 804. 01 May 2019 Restriction Practice 14

Restriction and non-statutory double patenting (cont. ) If it is unclear whether restriction should

Restriction and non-statutory double patenting (cont. ) If it is unclear whether restriction should be applied, an examiner should ask whether they would be inclined to apply a nonstatutory double patenting rejection if the claims were presented in different applications: • If yes, then restriction should not be required. • If no, then restriction may be appropriate, but remember that requiring restriction is at the examiner’s discretion and requires a showing of serious search and examination burden. May 2019 Restriction Practice 15

Breadth vs. patentable distinction

Breadth vs. patentable distinction

Breadth vs. patentable distinction Do not mistake variations in breadth for patentable distinctness. Claims

Breadth vs. patentable distinction Do not mistake variations in breadth for patentable distinctness. Claims should not be restricted if they define the same essential characteristics of a single disclosed embodiment of an invention. • Claims define the same essential characteristics when the claims: – Provide different definitions of the same invention, or vary only in breadth or scope of the invention. MPEP 806. 03 May 2019 Restriction Practice 17

Breadth vs. patentable distinction (cont. ) Claim 1. An ice cube tray for freezing

Breadth vs. patentable distinction (cont. ) Claim 1. An ice cube tray for freezing liquids comprising: a frame and multiple compartments within the frame. Claim 2. The ice cube tray of claim 1, wherein the multiple compartments are star-shaped. Claim 3. An ice cube tray for freezing liquids comprising: a frame and multiple compartments within the frame, wherein the compartments are polygonal. Claim 1 is broad while claims 2 and 3 are more narrow. The claims are not restrictable because claim 1 defines the same invention of a structure for making ice cubes, albeit in a broader way. All limitations of claim 1 are anticipated by the limitations of claims 2 or 3 and could serve as the basis for non-statutory double patenting if presented in separate applications. Accordingly, restriction would not be proper. May 2019 Restriction Practice 18

Combination-subcombination • • A combination contains two or more subcombinations or elements claimed together. Combination-subcombination can appear in various forms, as seen below. This list is not exhaustive. Where A, B, and C represent claim elements, “sp” indicates an element claimed specifically, and “br” indicates an element claimed broadly: o ABsp – Bsp o ABbr – Bsp o ABCsp- Bsp - Csp o ABsp. Csp- Bsp - Csp Illustrative examples of these types will follow. MPEP 806. 05(c), 806. 05(d) May 2019 Restriction Practice 21

Combination - subcombination (cont. ) • To support a restriction between a combination and

Combination - subcombination (cont. ) • To support a restriction between a combination and a subcombination a two-way test for distinctness and reasons for insisting on restriction are necessary. • Distinctness can be shown when: (i) The combination as claimed does not require the particulars of the subcombination as claimed for patentability (i. e. , to show novelty and non-obviousness of the combination), AND (ii) The subcombination has utility either by itself or in another materially different combination. • When these factors cannot be shown, the inventions are not distinct.

Does the subcombination (neomycin petrolatum ointment) have separate utility in another type of dressing or utility on its own (Yes/No)? – Yes. It may have separate utility in another type of dressing such as in a compression or other non-adhesive bandage. Is this enough to establish distinctness between the combination and subcombination (Yes/No)? – May 2019 No, because both requirements of the two-way test must be met. Restriction Practice 24

Summary: Knowledge check 1 ABsp – Bsp • • • The combination (wound dressing of claim 1) requires the particulars of the subcombination (ointment of claim 2) for patentability, even though the subcombination has utility either by itself or in another materially different combination, so this claim group pair does not meet the first part of the two-way combinationsubcombination test. While the ointment may have separate utility in another type of dressing, or utility on its own (i. e. , it meets part ii of the test), a restriction cannot be made because the two-way test requires meeting both requirements (i) and (ii). No distinctness - restriction would not be proper. May 2019 Restriction Practice COMBINATION Adhesive bandage Neomycin petrolatum ointment SUB Neomycin petrolatum ointment 25

Subcombinations usable together • Two or more claimed subcombinations, disclosed as usable together in

Subcombinations usable together • Two or more claimed subcombinations, disclosed as usable together in a single combination, are usually restrictable when: At least one subcombination as claimed can be shown to be separately usable or has utility other than in the disclosed combination, AND The subcombinations as claimed do not overlap in scope*, AND The subcombinations as claimed are not obvious variants of one another. *Not overlapping in scope means that the inventions have mutually exclusive limitations or the limitations of one claimed invention would not read on the limitations of the other claimed invention (and vice versa). • Example: a robotic eye has limitations that would not be included in a robotic hand vice versa, so they do not overlap in scope. Serious burden must also be shown to support a restriction between subcombinations. MPEP 806. 05(d), FP 8. 16 May 2019 Restriction Practice 29

Csp – Bsp - Cbr Can it be shown that the subcombination claims are separately usable, do not overlap in scope, and are not obvious variants (Yes/No)? Yes. Subcombination B (claim 4, neomycin ointment) can be used with a plastic bandage and subcombination C (claim 5, woven adhesive bandage) can be used without any ointment. Additionally, subcombination B and subcombination C do not overlap in scope and are not obvious variants. Is this sufficient to establish that each subcombination is distinct from the combination (Yes/No)? No. Both two-way distinctness (combination-subcombination) and serious burden must be shown. Sub B does not meet the two-way (combination/subcombination) test since the combination requires all of the particulars of the subcombination. However, Sub C may pass the test for reasons similar to Example 2, so the restriction requirement will result in two distinct groups: Group I: combination (claim 3) + Sub B (claim 4); Group II: Sub C (claim 5).

Subcombination B (claim 7, circular gauze pad) can be used without an adhesive woven bandage strip and subcombination C (claim 8, adhesive woven bandage strip) can be used without a circular gauze pad. Additionally, subcombination B and subcombination C do not overlap in scope and are not obvious variants. Is this sufficient to establish that each subcombination is distinct from the combination (Yes/No)? No. Both two-way distinctness (combination-subcombination) and serious burden must be shown. Sub B does not meet the two-way (combination/subcombination) test since the combination requires all of the particulars of the subcombination. Additionally, Sub C does not meet the two-way (combination/subcombination) test since the combination requires all of the particulars of the subcombination.
