Patent application titled: SYSTEMS AND METHODS FOR SPLIT TESTING EDUCATIONAL VIDEOS
Within is reference to an innovator's patent agreement:
In order to actively sue another company for patent infringement unprovoked, Khan Academy would have to violate what is known as an innovator’s patent agreement. Introduced by Twitter in 2012 in an effort to make patents more palatable to developers, the agreement is a contract that ensures a company that holds a patent is unable to use it for “offensive” purposes -- suing a company, for example -- unless it gets permission from the employee who came up with the idea or invention.
In this case, Khan Academy entered into an innovator's agreement with Matt Faus, a developer. Khan Academy did not respond to a request from comment.
The application is US 20150310753, and the application claims the benefit of U.S. Provisional Application No. 61/975,685, filed Apr. 4, 2014. WILSON, SONSINI, GOODRICH & ROSATI is prosecuting the case.
