This tab provides as many as 300 potential prior art references (patents) from US, EP, JP, CN, KR, WO, CA, DE, AU, FR, GB, RU, TW, and IN with the highest semantic similarity to the patent-at-issue. Semantic similarity is established by comparing the patent-at-issue’s first claim and abstract to the English titles, abstracts, and all claims of potential references (this is the default setting, see Change scope for more options). For further explanation and details, please refer to Glossary Look-ups.
To avoid redundancy, if any of the results in the Semantic list also show up in any of the other prior art tabs, a cross-reference tag will show. A cross-reference with previously considered patents in the prosecution or PTAB, second-degree art, or family prior art is tagged as follows:
- CONS - considered already in its prosecution history or PTAB proceedings
- 2nd - one of the 2nd-degree prior art results (a backward or forward citation of CONS)
- FAMI - one of the family prior art results
In addition to “List view,” Quality Insights also offers “Grid View” for Semantic Prior Art with the first figures and abstracts — along with additional important patent information — to facilitate a quick evaluation of relevant patents.
By default, the semantic prior art search is based on the first claim and abstract. However, you can change the Semantic Prior Art's search scope with the following steps:
- Click on "Change Scope"
- Click the text box to type in your own text
- or "Add text from claims"
- Once you are finished, click "Submit"
