What is the role of the specification in determining claim indefiniteness?
The specification plays a crucial role in determining claim indefiniteness. The MPEP emphasizes the importance of considering the specification: “Definiteness of claim language must be analyzed, not in a vacuum, but in light of: (A) The content of the particular application disclosure; (B) The teachings of the prior art; and (C) The claim interpretation that…
Read MoreHow should patent examiners approach double inclusion in claims?
Patent examiners should approach double inclusion in claims with careful consideration of the specific context and claim language. The MPEP 2173.05(o) provides guidance for examiners: “The facts in each case must be evaluated to determine whether or not the multiple inclusion of one or more elements in a claim gives rise to indefiniteness in that…

Read MoreWhat are “open-ended” numerical ranges in patent claims?
What are “open-ended” numerical ranges in patent claims? “Open-ended” numerical ranges in patent claims refer to ranges that have only one defined boundary. The Manual of Patent Examining Procedure (MPEP) 2173.05(c) states: “Open-ended numerical ranges should be carefully analyzed for definiteness.” Examples of open-ended ranges include: “greater than 5” “at least 10” “below 100” These…
Read MoreWhat are “narrow and broader ranges” in the same claim?
What are “narrow and broader ranges” in the same claim? “Narrow and broader ranges” in the same claim refer to situations where a patent claim includes both a specific value or narrow range and a broader range that encompasses the narrow range. The MPEP 2173.05(c) addresses this issue: “A broad range or limitation together with…
Read MoreHow does the MPEP address “about” in numerical range limitations?
How does the MPEP address “about” in numerical range limitations? The MPEP 2173.05(c) addresses the use of “about” in numerical range limitations. It states: “The use of ‘about’ in conjunction with a specific number or numerical range in a claim must be evaluated on a case-by-case basis.” The term “about” is often used to indicate…
Read MoreWhat is the impact of using a trademark as a generic term in a patent claim?
Using a trademark as a generic term in a patent claim can have significant negative consequences: It may render the claim indefinite under 35 U.S.C. 112(b). It constitutes improper use of the trademark. It can potentially lead to the loss of trademark rights. The MPEP 2173.05(u) states: “In fact, the value of a trademark would…
Read MoreHow does double inclusion affect Markush groups in patent claims?
Double inclusion in Markush groups generally does not cause issues with claim indefiniteness. The MPEP 2173.05(o) provides specific guidance on this topic: “The mere fact that a compound may be embraced by more than one member of a Markush group recited in the claim does not lead to any uncertainty as to the scope of…
Read MoreHow does double inclusion affect device claims in patents?
Double inclusion in device claims can potentially lead to indefiniteness issues. The MPEP 2173.05(o) provides specific guidance on this matter: “On the other hand, where a claim directed to a device can be read to include the same element twice, the claim may be indefinite.” The MPEP cites the case of Ex parte Kristensen to…
