Semantic Prior Art

Semantic Prior Art — Find Patents Through Semantic Similarity

Starred (★) prior art are those with high semantic similarity within the designated scope

The starred  (★) prior art found with high semantic similarity has a higher percentage of semantic similarity to the patent-at-issue than the aggregated average similarity of all US patents to their family members and §102/§103 prior art. 

Simply put, the prior art (★) found with high semantic similarity is more similar to the patent-at-issue than its family/§102/§103 prior art.

Under Cross-reference:

• CONS (Considered) -  This reference already appears in the patent’s prosecution history or PTAB proceedings.
• 2nd - This reference is in the 2nd-degree prior art results (a backward or forward citation of CONS).
• FAMI (Family) - This reference is in the family prior art results.

Semantic Prior Art with high semantic similarity (★) is also included within the Potential §103 prior art on the Overview page.
