USPTO: Do Not Send Mail To PTO’s DC Address

Although the USPTO moved to Virginia almost two years ago, it has still been accepting mail at its DC address.  That practice is changing: 

Effective April 4, 2004, all mail sent to the USPTO’s Washington DC 20231 address will be returned to sender.  Such returned mail will not be considered proof of filing.  Unless otherwise indicated, patent-related mailings should be sent to: Commissioner for Patents P.O. Box 1450 Alexandria, VA 22313-1450.

    The “Mock Jury” has been Patented

    This post was relatively humorous. I found it as a recent news event on Dennis Crouch’s Patent News blog. Apparently, the method for “conducting a mock trial” has been patented.
