II.USPTO INTERNET SITE
The USPTO website (www.uspto.gov ) provides a wealth of information to all users. The USPTO website offers links to news and notices (such as announcements, press releases, Official Gazette Notices and Federal Register Notices), USPTO contacts and addresses, activities and education related pages (such as the PTDL program and the Kids Pages), patent specific information (such as issued patents and published patent applications, general information pertaining to applying for a patent, electronic filing of patent applications, and reference materials such as the MPEP and examination guidelines), and trademark specific information (such as the Trademark Manual of Examining Procedure and the U.S. Trademark Electronic Search System (TESS)). In addition, the website allows downloading of a variety of USPTO forms (including PCT forms), ordering copies of patents and trademarks, accessing a list of all current fees, paying patent maintenance fees, replenishing deposit accounts, accessing various legal materials, linking to related websites, etc.
The Patent Electronic Business Center (EBC) assists USPTO customers with electronic patent application submissions via the Electronic Filing System (EFS-Web) and with the review of patent applications in Public and Private PAIR. The EBC offers online electronic filing information, instructional material, PatentIn and Checker support and is available to assist users through one-on-one support during its normal business hours. The EBC also serves as a liaison in directing customers to other USPTO organizations that can address their specialized business issues and needs. The hours of operation of the EBC are Monday through Friday 6 a.m. – midnight (ET). The EBC can be reached by telephone at 866-217-9197 (toll-free) or 571-272-4100. The EBC may be reached by email at firstname.lastname@example.org and by fax at 571-273-0177.
The Patent Grants Database provides access to the full-text of all U.S. patents issued since 1976, and to the full-page images of all U.S. patents issued since 1790.
The Patent Applications Database provides both full-text and full-page images of all U.S. patent applications published since March 15, 2001.
Status information relating to patent applications is available through the Patent Application Information Retrieval (PAIR) system. There is both a public and private side to PAIR. In public PAIR, information is available relating to issued patents, published patent applications, and applications to which a patented or published application claims domestic priority. In private PAIR, an applicant (or his or her registered patent attorney or registered patent agent) can securely track the progress of his or her application(s) through the USPTO. Private PAIR makes available information relating to unpublished patent applications, but the applicant must associate a Customer Number with the application to obtain access. See MPEP § 403 for Customer Number practice.
(d)Image File Wrapper (IFW)
The Image File Wrapper (IFW) system uses image technology to replace the paper processing of patent applications in the Office. Paper components of these application files (including the specification, oath or declaration, drawings, information disclosure statements, amendments, Office actions, and file jacket notations) have been scanned to create electronic image files. For patent applications in the IFW system, the IFW file is the Official file and no access is granted to the original paper document sheets used to create the IFW file. All processing and examination is conducted using the electronic images instead of the paper source documents.
If an IFW file has been created for a patented application, published application, or an application to which a patented or published application claims domestic priority, the IFW file (with the exception of non-patent literature) is accessible through public PAIR. All patent applications filed after June 30, 2003 have been scanned into the IFW system and will be available in public PAIR as soon as they have been published or patented. Pending applications filed before June 30, 2003 are scanned into IFW as incoming papers are received in the Office. Non-patent literature (NPL) may be viewed using private PAIR (if an IFW file has been created) or obtained from the USPTO Office of Public Records.
Questions about IFW images viewed in PAIR should be directed to the Patent EBC.
(e)Assignments on the Web (AOTW)
Assignment information is available for issued patents and published applications recorded since August 1980. AOTW is available at
www.uspto.gov/patent/laws-and-regulations/ power-attorney-and-assignment/assignments-web-aotw. Questions or concerns regarding the data displayed may be directed to the Assignment Services Division at email@example.com or 571-272-3350.
(f)Global Patent Search Network
The Global Patent Search Network (http://gpsn.uspto.gov) hosted by the USPTO provides public access to English language translations of a large subset of Chinese patent documents created by machine translation technology. Due to limitations in machine translation technology, the English translation of the patent may not precisely reflect the content of the original patent document. The original patent document images are the authoritative source of the patent content. The translation does not provide an interpretation or determination of any kind by the USPTO. The translation is not intended to, and does not, create any right or benefit, substantive or procedural, enforceable at law or in equity by a party against the United States, its departments, agencies, instrumentalities, entities, officers, employees or agents, or any other person. The “***” shows words which cannot be translated by the software. Text contained within drawings is not translated.
2.Transacting Electronic Business
(a)Filing Applications and Other Documents
The Electronic Filing System-Web (EFS-Web) allows customers to electronically file patent application documents securely via the Internet. See the EFS-Web Legal Framework ( www.uspto.gov/ patents-application-process/applying-online/ legal-framework-efs-web-06april11) for submissions via EFS-Web. See also MPEP § 502.05.
