of the project The process described in this section is that used for the USPTO pilot. Patent applicants The USPTO pilot, officially announced in the USPTO's Official Gazette of 26 June 2007, was initially restricted to patent applications from Technology Center 2100 (Computer Architecture, Software and Information Security) that are voluntarily submitted to the project by the owner/assignee. The extended pilot has expanded to include so-called Business Methods patents (class 705) that fall under Technology Center 3600. To be eligible for Peer To Patent review, a patent application must be filed during the period covered by the pilot. Furthermore, the USPTO tries to provide a representative sample of current patents by limiting the number of applications from any given applicant. Incentives for submitting an application to the project include: Expedited review. Public review begins one month after publication of the application. Review continues for four months, after which the patent examiner conducts an expedited examination of the patent application. Potentially stronger patents. If Peer to Patent review works as expected, patents that survive the process have already undergone considerable scrutiny and will be less at risk of a successful challenge later. Public service. Applicants can feel they are contributing to a valuable experiment in new models and technologies for public decision-making. Applicants follow a procedure described on the project's web site to submit patent applications for review. Community review After a patent is published on the Peer To Patent web site, the public can post not only instances of possible prior art, but other useful comments such as common industry terms that might describe the patent. These terms, or Folksonomy tags, are useful to help other experts find prior art. The review process emphasizes and supports group collaboration in the following ways. Communication: To notify people who sign up on the web site about new applications, summaries are distributed regularly by email. People visiting the web site can easily see the titles of recent applications and other useful information. Productivity: To keep discussion constructive and on topic, each application's site has a facilitator, whose job includes inviting new participants, reminding participants of their goals, and flagging inappropriate postings. Self-regulation: A key contribution by participants is to rate prior art submitted by their fellow participants for a particular application. The ten pieces that receive the highest rating are submitted at the end of the review period to the patent examiner assigned
