What “public domain” means for patents: These patents were filed in 2008. Under US law, utility patents expire 20 years from their filing date — meaning the inventions below become freely available in 2028. Anyone can manufacture, use, sell, or import these technologies without a license or royalty payment. This opens significant opportunities for engineers, startups, and manufacturers.

Disclaimer: Expiration status is calculated from filing date + 20 years. Some patents may have maintenance fee lapses, terminal disclaimers, or continuation patents that affect their effective status. Always verify with a registered patent attorney before relying on expiration status for commercial decisions.
