Family Prior Art - Ranked by Application Date (Ascending Order)
In the Family Prior Art tab, the patents are listed by “Application Date” in ascending order, according to their potential relevance as prior art references. In other words, the earlier the date, the more relevant the prior art may be.
Prior Art Finder - Ranked by Legal Basis (35 U.S.C § 102 First, and Then 35 U.S.C § 103)
In the Prior Art Finder tab, the patents are listed by their “Legal Basis.”
For the first degree prior art, the patents are listed in favor of being cited based on 35 U.S.C § 102. Then they are listed by being cited based on 35 U.S.C § 103.
For the second degree prior art, there are two layers of citations. The patents that are only cited based on 35 U.S.C § 102 forward/backward citations will be presented first, followed by the patents cited based on any of the 35 U.S.C § 102/103 forward/backward citations. The patents cited based on only 35 U.S.C § 103 forward/backward citations will be listed at the end.
Semantic Prior Art - Ranked by the Relevance of the Abstract and Claims
Each prior art reference in the semantic prior art tab is ranked by the relevance of the abstract and claims between the prior art reference and the patent at issue.
The relevance is calculated based on the similarity of the keywords, the similarity of related words, and the relationship between the keywords (for example, the sequence or the distance between the keywords.)
