We score subject matter expertise using a proprietary algorithm that automatically combines your patent number with the following:

  • an expert's experience in similar CPC groups and subgroups, as well as experience in the same patent family, and

  • machine learning that compares language in CVs and declarations to the claims and specifications of your patent at issue

This generates a unique score to determine which experts have the subject matter expertise to help you win your case.

High means the expert has one of the following:

  • At least 1 appearance on an IPR in the same sub-group (e.g., A01B 33/00); or

  • At least 3 appearances on IPRs in the same group (e.g., A01B 33); or

  • At least 5 appearances on IPRs in the same subclass (e.g., A01B); or

  • At least 1 appearance on an IPR involving a patent in the same patent family.

Medium means the expert has at least one of the following:

  • 1-2 appearances in the same group (e.g., A01B 33); or

  • 3-4 appearances in the same subclass (e.g., A01B); or

  • 10+ appearances in the same class (e.g., A01)

Low means the expert has at least one of the following:

  • 1-2 appearances in the same subclass (e.g., A01B); or

  • 5-9 appearances in the same class (e.g., A01)

If a patent number search results in more than 20 experts, the top 10% of experts are marked as Very High.

If an examiner has worked on an IPR for a patent in the same family as the patent number searched, they are indicated by a β€œ+” next to the experience score.

Experts that do not match any of the above criteria are not included in the search results.
