Questions
Restriction: Definition & Characteristics
A tool used by the USPTO to limit the substantive examination of a patent application to a single invention
Set forth in 35 USC 121 It is discretionary It can be set forth any time during prosecution A proper restriction requirement establishes:
The existence of two or more independent or distinct inventions (See MPEP §802; §806), and a
serious burden on the examiner (See MPEP §803.02; §806.04; §808.01-02), e.g., separate status in the art; separate classification; divergent field of search
Example of Distinct Inventions
The application contains claims to different inventions: polypeptides polynucleotides antibodies diagnostic kit
Applicant must elect an invention for examination Election may be done with or without traverse. If the
restriction is traversed, applicant can petition to Group Director.
Divisional Application may be filed covering non-elected invention
Categories of Related Inventions
Product and process of use; MPEP§806.05 (h) Product and Process of making; MPEP§806.05 (f) Process and apparatus for its practice; MPEP§806.05 (e) Apparatus and product; MPEP§806.05 (g) Combination and subcombination ; MPEP§806.05 (a-c) Subcombinations useable together; MPEP§806.05 (d) Intermediate and final product MPEP§806.04(b) Product, process of making, process of using MPEP§806.05 (i)
Linking Claims: Definition and Characteristics
One or more claims inseparable from claims to two or more otherwise properly divisible invention; MPEP §809.
If deemed allowable, restriction must be withdrawn.
Upon withdrawal of the restriction, double patenting rejections may come in to play; protection of 35 USC 121 is no longer afforded
Example of a Linking Claim
1. A pharmaceutical composition comprising an inorganic or an organic compound.
2. The pharmaceutical composition of claim 1 wherein the organic compound is an estrogen.
3. The pharmaceutical composition of claim 1 wherein the inorganic compound is water.
4. A method of treating infertility using the pharmaceutical composition of claim 1.
Rejoinder
If the invention under examination is a product, once the product has been deemed allowable, the process of making and using the same must be allowed as well.
In re Ochiai; MPEP 821.04 Sua sponte rejoinder by the USPTO Process of making and using claims must be of the
same scope as the product claims
Restriction vs. Unity of Invention
For 111 applications (applications filed under 35 USC 111) the standard is set forth in 35 USC 121; the standard is expressed as “independent”, “distinct”, “related” inventions
For 371 applications (applications filed under 35 USC 371), the standard is 35 USC 372 and 35 USC 121; the standard is expressed as “unity of invention”, “common technical feature”
Divisional Application and Non-Elected Subject matter
Independent or distinct invention carved out of a pending application claiming only subject matter disclosed in the earlier application, i.e., non-elected invention Diagnostic kit Antibodies polynucleotides
Filed in response to a restriction requirement The priority date is the original application’s priority
date A divisional application cannot be subject to a DP
rejection over its parent application/patent.
Double Patenting: Purpose & Types
The purpose of DP rejections is to prevent unjustified extension of patent term
DP rejections are based on an issued patent or pending patent application with the same assignee
There are two types of Double patenting rejections:
Statutory Double Patenting under 35 USC §101 Non-Statutory Double Patenting which is based on
anticipation or obviousness analyses
Statutory Double Patenting : Characteristics and Cure
Identical subject matter is being claimed in the claims under examination and those of a commonly owned patent or patent application
The claims under examination and those in a commonly owned patent or patent application encompass the same embodiments
Claims subject to the DP rejection must be cancelled or amended
A terminal disclaimer does not overcome a DP rejection under 35 USC 101
Non-Statutory Double Patenting
It can be based on a anticipation or obviousness type analyses
It can be overcome by cancelling or amending the claim
It can also be overcome by a terminal disclaimer
