We are working to create a site that helps track the estimated expiration dates of software patents

Our goal is to make a community resource that lists the estimated expiration dates of important software patents. We aim to do this by making it easy for a collaborative effort to add, track and search for patents that affect your software or software you are interested in.

The rise of software patent litigation has put a spotlight on software patents and we hope so create a simple resource for tracking when an important patent enters the public domain.

Example

Patent: Fixed-rate block-based image compression with inferred pixel values

Estimated expiry: Oct 2, 2017

A.K.A: S3TC or S3 Texture Compression patent

Importance: The wide use of S3TC has led to a requirement for OpenGL drivers to support it, but the patent-encumbered status of S3TC presents a major obstacle to open source implementations.
