Legal
Terms of Service
Provisional notice
This page describes how this website works today. It is not the full legal agreement for the 287a platform — that will be published, and presented for acceptance, when accounts reopen. Last updated 22 August 2026.
What this site is
287a.com is an informational website operated by 287a LLC. It publishes background on patent marking and on the 287a service. It does not offer accounts, does not accept sign-ups, does not take payment, and does not host published marking pages.
Use of the site
You may read, link to, and quote these pages. The text and design are the property of their respective owners; the statutory text quoted here is in the public domain. The site is provided as-is, without warranties of any kind, and we may change or withdraw any part of it at any time.
This is not legal advice
Nothing on this site is legal advice, and reading it does not create an attorney-client relationship. Patent marking obligations depend on your products, your portfolio and your jurisdiction. Always consult your own attorney when evaluating your patent marking requirements.
Terms for the platform
The 287a platform is being rebuilt. When accounts reopen, the terms governing them will be published here and presented for acceptance before any account is created. Until then, no terms on this page create an account relationship of any kind.
Existing 287a accounts
If you hold a 287a account created before this notice, the Terms of Service with an effective date of 06/01/24 are the terms that were in effect for it. For a copy of that document, or for any question about your account or your data, email support@287a.com.
