What is the purpose of a claim chart in patent interference proceedings?
A claim chart in patent interference proceedings serves as a crucial tool for comparing and analyzing the claims of the parties involved. According to MPEP 2304.02(b), when suggesting an interference, the applicant must:
“For each count, provide a claim chart comparing at least one claim of each party corresponding to the count and show why the claims interfere within the meaning of § 41.203(a).”
The purpose of the claim chart is to:
- Visually represent the correspondence between claims and counts
- Facilitate the comparison of claims from different parties
- Demonstrate how the claims interfere with each other
- Aid the examiner in verifying that the formal requirements for suggesting an interference are met
By providing a clear, side-by-side comparison, the claim chart helps in identifying the interfering subject matter and supports the argument for declaring an interference.
