What makes a “Use” claim definite according to patent law?
A “Use” claim can be considered definite if it clearly recites active, positive steps that delimit how the use is practiced. The MPEP 2173.05(q) provides guidance on this matter, citing the case of Ex parte Porter, 25 USPQ2d 1144 (Bd. Pat. App. & Inter. 1992): “In the case of Ex parte Porter, 25 USPQ2d 1144…
Read MoreAre “use” claims ever acceptable in US patent applications?
While “use” claims are generally problematic in US patent applications, there are rare instances where they might be acceptable: Certain process claims: If the claim clearly implies the steps involved, it might be considered definite. However, this is risky and not recommended. Product-by-process claims: These are not strictly “use” claims but can describe a product…

The USPTO’s Manual of Patent Examining Procedure (MPEP) 806.05(f) provides guidance on determining if a process can make a materially different product. The key considerations are: The claimed process must be capable of producing a product that is materially different from the one claimed. The difference must be significant and not merely a trivial variation.…

What is the “two-way distinctness” test for process and apparatus claims? The “two-way distinctness” test is a criterion used by patent examiners to determine whether process and apparatus claims are distinct for the purposes of restriction requirements. According to MPEP 806.05(e): “Process and apparatus for its practice can be shown to be distinct inventions, if…
Read MoreWhat are the conditions for a three-way restriction requirement in a patent application?
A three-way restriction requirement in a patent application can only be made under specific conditions. According to MPEP 806.05(i): “Where claims to all three categories, product, process of making, and process of use, are included in a national application, a three way requirement for restriction can only be made where the process of making is…
Read MoreWhat is the significance of a process “specially adapted for” making a product in restriction practice?
In patent restriction practice, a process “specially adapted for” making a product has special significance. The MPEP 806.05(i) states: “Where an application contains claims to a product, claims to a process specially adapted for (i.e., not patentably distinct from, as defined in MPEP § 806.05(f)) making the product, and claims to a process of using…
Read MoreWhat is the significance of the “materially different” standard in MPEP 806.05(f)?
The “materially different” standard in MPEP 806.05(f) is crucial for determining distinctness between process and product claims. Its significance lies in: Establishing distinctness: The standard helps determine if the process and product are truly separate inventions. Guiding restriction requirements: It provides a basis for examiners to issue restriction requirements. Defining the scope of examination: It…

What is the significance of the phrase “another and materially different” in MPEP 806.05(f)? The phrase “another and materially different” in MPEP 806.05(f) is crucial for establishing distinctness between a process of making and a product made. It signifies that: For the process: It must be capable of making a product that is significantly different…
Read MoreWhat options does an applicant have when facing a restriction requirement for product, process of making, and process of using claims?
When an application contains claims to a product, process of making, and process of using, the applicant may face a restriction requirement. According to MPEP 806.05(i): “Where an application contains claims to a product, claims to a process specially adapted for (i.e., not patentably distinct from, as defined in MPEP § 806.05(f)) making the product,…
Read MoreHow can an applicant respond to a restriction requirement between process and product claims?
When faced with a restriction requirement between process and product claims under MPEP 806.05(f), an applicant has several options: Elect one group: Choose either the process or product claims for examination. Traverse the requirement: Argue against the distinctness assertion by: Demonstrating that the process cannot make a materially different product. Showing that the product cannot…
