In a letter recently forwarded to Congress, the AFL-CIO warned that the current statutory reforms suggested for the U.S. patent system would weaken the strength of U.S. patents by limiting damages for patent infringement, as well as by increasing the ways to challenge patents. It further stated that the reforms would undermine the global position of the United States in patent matters. Other entities, including pharmaceutical companies and research universities have expressed opposition stating that the reform will substantially weaken the value of patents, thus stifling innovation.

While the legislation was expected to proceed, House members halted the movement so as not to rush the measure. Corporations such as Microsoft and Cisco Systems, as well as other legislation supporters see the measure as remedying weaknesses in the current patent system which they believe hinders innovation and the ability for patent holders to protect patent rights.
