What qualifies as a patent?

Sometimes people ask what qualifies for a patent, a trademark, or a copyright. The answer is usually somewhat instinctive: it must be something they created; it can’t be something that has already been around for a long time without that person’s contribution. This kind of instinctual analysis inherently reflects a notion that whatever has recently been created and has value is not part of the public domain and could at least, theoretically, belong to one owner. It is a very important part of intellectual property theory that, once something is in the public domain, intellectual property rights should never be allowed to take it back out.

How do patents help in the public domain?

The patent system was designed to promote public innovation and manage the public domain.5By encouraging other inventors to work around the patent to create improved, alternative technologies that might not have otherwise been developed, patents encourage creativity and innovation in society. They can also reward inventors for their hard work and ingenuity by giving them the right to control the manufacture and sale of their invention. In this way, patents “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” as delineated in Article I of the Constitution.6

Why is inter partes reexamination so effective?

According to the data, inter partes reexamination is also a fair and effective proceeding that allows third party requesters to challenge improvidently granted patents and raise valid new questions of patentability. Requests for inter partes reexamination are granted at incredibly high rates. This may be due to some amount of self-selection that limits inter partes filings to those requesters sufficiently confident in their arguments to risk estoppel. 32 The following table shows how only four percent of all inter partes requests have been denied since the start of inter partes reexamination proceedings in 1999.

One major critique is that the Patent Office's process for reviewing patent applications does not involve an adequate search for relevant prior art in different technological fields.9It can be especially difficult to identify prior art information with respect to new technologies such as computer software.10Another common criticism of the USPTO is that it is too subject to political influence, as important interest groups that exert pressure on policymakers in Congress and the USPTO can directly shape patent policy.11In addition, many argue that the laws and regulations governing the behavior of the USPTO do not provide the incentives needed to issue valid patents, and there is a lack of penalties to the Patent Office for incorrectly issued patents.12It has also been asserted that US patent examination is deficient as compared to other national patent offices. Some have alleged that the USPTO has higher rates of acceptance and low levels of review, particularly compared to Japan's and the European Union's patent offices.13

Why is the USPTO under scrutiny?
