We've just announced our first prior art search contest at Patexia! The contest centers around a charge pump circuit used in a voltage controlled oscillator in US patent 5,825,640. The object is to find materials (patents, papers, etc.) which detail this circuit published before the patent (a.k.a. prior art).  We're offering a $5000 prize for the best submission.

A lot of work went into preparing and spreading the word about the contest, so we're very excited to see the results.

You can check out the contest and read more here.
