In 2004, Müller received the support of corporate sponsors 1&1, Red Hat and MySQL for launching NoSoftwarePatents.com, which opposed the European Commission's proposed directive on the patentability of computer-implemented inventions.
[15] Jointly with the FFII, Müller received the "CNET Networks UK Technology Award" in the "Outstanding Contribution to Software Development" category.
[17][18][19] In January 2011 Müller published an article suggesting that "evidence is mounting that different components of the Android mobile operating system may indeed violate copyrights of Sun Microsystems, a company Oracle acquired a year ago."
According to Ed Burnette, a ZDNet blogger, Google published those files on its web site to help developers debug and test their own code.
[22] Two days after his original assertions Müller claimed to have found the files in the official source availability packages of device makers Motorola, LG and Samsung.
[27] Müller amplified[28] a Huffington Post article by Edward Naughton, an intellectual property lawyer[29] who has previously represented Microsoft,[30][31] who suggested that Google likely violated the GPL by copying Linux header files.
