Why it's free to use

  • Published November 19, 2009, and no patent has issued anywhere in its US family since.
  • Nothing has been filed in its family for more than seven years, so it is very unlikely to still be pending.
  • This status is inferred from USPTO records. Confirm it on Patent Center before relying on it.
