Before discussing the patentable subjects regulated in 35USC, I am trying to learn something about the sources of us patent law.
First, the US Constitution’s statement of the congress’s power to “promote the Progress of Science and useful Arts by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.” (comparing to the PRC Constitution, section 20: The state promotes the development of the natural and social sciences, disseminates knowledge of science and technology, and commends and rewards achievements in scientific research as well as technological innovations and inventions.)
And secondly the federal statutes and regulations. Then the most important , the case law. I don’t have much experiences to read the opinions of the Federal Circuit and a question confuses me for quite a long time: I don’t know the intention of “[]” in the text of different opinions , such as “n the absence of any indication of illegal tying……”. Who can tell me WHY? |
