806.05(d) Subcombinations Usable Together [R-5] - 800 Restriction in Applications Filed Under 35 U.S.C. 111; Double Patenting
806.05(d) Subcombinations Usable Together [R-5]
Two or more claimed subcombinations, disclosed as usable together in a single combination, and which can be shown to be separately usable, are usually restrictable when the subcombinations do not overlap in scope and are not obvious variants.
>To support a restriction requirement where applicant separately claims plural subcombinations usable together in a single combination and claims a combination that requires the particulars of at least one of said subcombinations, both two-way distinctness and reasons for insisting on restriction are necessary. Each subcombination is distinct from the combination as claimed if:
(A) the combination does not require the particulars of the subcombination as claimed for patentability (e.g., to show novelty and unobviousness), and
(B) the subcombination can be shown to have utility either by itself or in another materially different combination. See MPEP § 806.05(c). Furthermore, restriction is only proper when there would be a serious burden if restriction were not required, as evidenced by separate classification, status, or field of search.
Where claims to two or more subcombinations are presented along with a claim to a combination that includes the particulars of at least two subcombinations, the presence of the claim to the second subcombination is evidence that the details of the first subcombination are not required for patentability (and vice versa). For example, if an application claims ABC/B/C wherein ABC is a combination claim and B and C are each subcombinations that are properly restrictable from each other, the presence of a claim to C provides evidence that the details of B are not required for the patentability of combination ABC.
Upon determining that all claims directed to an elected combination invention are allowable, the examiner must reconsider the propriety of the restriction requirement. Where the combination is allowable in view of the patentability of at least one of the subcombinations, the restriction requirement between the elected combination and patentable subcombination(s) will be withdrawn; furthermore, any subcombinations that were searched and determined to be allowable must also be rejoined. If a subcombination is elected and determined to be allowable, nonelected claims requiring all the limitations of the allowable claim will be rejoined in accordance with MPEP § 821.04. <
Form paragraph 8.16 may be used in restriction requirements between subcombinations.
**>¶ 8.16 Subcombinations, Usable Together
Inventions [1] and [2] are related as subcombinations disclosed as usable together in a single combination. The subcombinations are distinct if they do not overlap in scope and are not obvious variants, and if it is shown that at least one subcombination is separately usable. In the instant case subcombination [3] has separate utility such as [4]. See MPEP § 806.05(d).
The examiner has required restriction between subcombinations usable together. Where applicant elects a subcombination and claims thereto are subsequently found allowable, any claim(s) depending from or otherwise requiring all the limitations of the allowable subcombination will be examined for patentability in accordance with 37 CFR 1.104. See MPEP § 821.04(a). Applicant is advised that if any claim presented in a continuation or divisional application is anticipated by, or includes all the limitations of, a claim that is allowable in the present application, such claim may be subject to provisional statutory and/or nonstatutory double patenting rejections over the claims of the instant application.
Examiner Note
1. This form paragraph is to be used when claims are presented to subcombinations usable together ( MPEP § 806.05(d)).
2. In bracket 3, insert the appropriate group number or identify the subcombination.
3. In bracket 4, suggest utility other than with the other subcombination.
4. Conclude restriction requirement with one of form paragraphs 8.21.01 through 8.21.03.
<The examiner must show, by way of example, that one of the subcombinations has utility other than in the disclosed combination.
Care must be taken to determine if the subcombinations are generically claimed.
Where subcombinations as disclosed and claimed are both (a) species under a claimed genus and (b) related, then the question of restriction must be determined by both the practice applicable to election of species and the practice applicable to related inventions. If restriction is improper under either practice, it should not be required ( MPEP § 806.04(b)).
If applicant proves or provides an argument, supported by facts, that the other use, suggested by the examiner, cannot be accomplished or is not reasonable, the burden is on the examiner to document a viable alternative use or withdraw the requirement.
