Blog Comment Policy
Blogs on the USPTO Web site do not represent official USPTO communications. The Office of Public Affairs manages USPTO blogs as a portal for information from the USPTO.
The USPTO provides moderation of blogs on its Web site: all comments will be reviewed before posting. Participants are expected to treat each other, as well as our agency and our employees, with respect. The USPTO will not post comments that are offensive, are clearly “off topic”, or promote commercial services or products. Comments that make unsupported accusations will also not be posted. The USPTO will not edit or alter individual blog comments.
Any references to commercial entities, products, services, or other nongovernmental organizations or individuals that remain on the site are provided solely for the information of individuals using the blog. These references are not intended to reflect the opinion of USPTO, the United States, or its officers or employees concerning the significance, priority, or importance to be given the referenced entity, product, service, or organization. Such references are not an official or personal endorsement of any product, person, or service, and may not be quoted or reproduced for the purpose of stating or implying USPTO endorsement or approval of any product, person, or service.
- Only comments that comply with this blog use policy will be approved for posting.
- The use of vulgar, offensive, threatening or harassing language is prohibited.
- Blog public comments should be limited to comments related to the posted topic. The blog is not the proper place to express opinions or beliefs not directly related to that topic.

Copyrights are administered by the Copyright Office, a division of the Library of Congress. Copyright law (17 U.S.C. § 105) states that all materials created by the United States government are in the public domain. However, there are restrictions on use.
Anyone incorporating a work of the U.S. Government into a copyrighted work should be aware of 17 U.S.C. § 403. This section requires a copyright notice to contain a statement identifying what portions of the work consist of a work of the U.S.Government. Failure to do so could result in loss of copyright protection for the entire work.
WARNING: Not all materials on the USPTO Web site were created by the U.S. Government. Some have been published by permission of the creators, and that permission is not generally transferrable. If a copyright is indicated on a video, photo, graphic, or other material, permission to copy these materials must be obtained from the original source. Please note that many photos used on this Web site are copyrighted. Photo credits may be identified within the caption or embedded in the “alt tag”.

Use of USPTO Seal
The USPTO does not authorize the use of either its seal or logo on any other Web sites.
For Web site security and to ensure that USPTO Web services remain available to the general public, the USPTO monitors network traffic to identify unauthorized attempts to upload or change information, deny service, otherwise cause damage or access non-public information. Unauthorized attempts to upload information or change information are strictly prohibited and may be punishable under the United States criminal code (18 U.S.C. § 1030). Information regarding possible violations of law may be provided to law enforcement officials.
Any activity or operation, whether generated automatically or manually, that results in or has the potential to result in denial or decrease of service for other customers may be denied access to uspto.gov Web resources without notice. If you believe your IP address may have been blocked, you may contact the Webmaster for instructions.
Use of USPTO Databases
Interactive access to USPTO databases is intended for use by the general public. Due to limitations of equipment and bandwidth, the online databases are not intended to be a source for bulk downloads of USPTO data. Bulk data may be separately obtained from USPTO, either for free or at the cost of dissemination, depending on product (see the USPTO Products and Services Catalog). Individuals, companies, IP addresses, or blocks of IP addresses who, in effect, deny or decrease service to the general public by generating unusually high numbers of daily database accesses (searches, pages, or hits), whether generated manually or in an automated fashion, may be denied access to these servers without notice.
