Jim: Don't know why GAMCO has stopped reporting patents; but, IDCC has been receiving patents issued this year.

The USPTO issues an "Official Gazette for Patents" which is a weekly listing of patents issued.

"The Official Gazette for Patents is published each Tuesday in electronic form only, and contains bibliographic text and a representative drawing from each patent issued that week. Please note that the Official Gazette Notices are also included in each issue."

On a quick look, I don't know how GAMCO came up with his listings as the Gazette format is a little confusing. The following is one of the IDCC patents in the latest weekly listing:


United States Patent 10,271,318
