Legal Late last week, Nokia dropped what many consider to be a bomb on the WebM project: a list of patents that VP8 supposedly infringes in the form of an IETF IPR declaration. The list has made the rounds around the web, often reported as proof that VP8 infringes upon Nokia's patents. All this stuff rang a bell. Haven't we been here before? Yup, we have, with another open source codec called Opus. Qualcomm and Huawei made the same claims as Nokia did, but they turned out to be complete bogus. As it turns out, this is standard practice in the dirty business of the patent licensing industry.

There is no open source license that I know of that requires you to not patent anything you discovered.

No, but there are ones that require you to license any patents you have in the code on a royalty free basis to anyone who receives the code under the terms of the license. The GPL for example (Section 11 specifically). The net effect is therefore the same.
