United States Patent and Trademark Office
The United States Patent and Trademark Office (USPTO) is known for granting large numbers of software patents.
According to a 2004 paper by Bessen and Hunt, the USPTO approves about 70 software patents per day.(see page 47) Other sources have said that in 2006 the USTPO granted just over 40,000 software patents, which is 110 per day, seven days per week.
The USPTO is an agency of the US government's Department of Commerce.
 Specifically excluded
 Examination guidelines
- 1996: Examination Guidelines for Computer-Related Inventions (The date, 1996, is given by Martin Goetz but the document itself does have a date - I don't know how we'd verify if this is still the 1996 version or if this link now points to an updated verion)
- 2007: new guidelines were issued, raising the standard for obviousness, following the ruling in KSR v. Teleflex (2007, USA)
- 2009, 2010: Interim guidelines were issued following the CAFC's decision on in re Bilski, and further interim guidelines were published following the Supreme Court's decision in Bilski v. Kappos. See: USPTO 2010 consultation - deadline 27 sept. (As of October 2010, final revised guidelines are not yet available) (There's an interesting article about the change in "obviousness" here)
 Key people
 Quality getting worse
Despite the USPTO's public comments about improving examination, it appears the real change is that quality has actually dropped. A 2013 study found that the "allowance rate" increased by 20% from 2009 to 2012. This confirms that legislation such as the America Invents Act are so watered-down and corrupted that they have no positive effect. Reform doesn't work; we need to exclude software from the patent system.
 Examiners stuck for time
Examiners in the USPTO have on average 20 hours to examine each application.
 Procedural notes
More info sought: there is an "Office of First Filing" and an "Office of Second Filing".
