Microdevices and Methods of Manufacture
United States Patent 9353313
A method of manufacturing one or more microdevices may include forming a liquid dispersion containing cellulose nanocrystals (CNC), depositing the liquid dispersion containing the CNC on a substrate, drying the liquid dispersion containing the CNC to form a solid film on the substrate, where the liquid dispersion contains a sufficient concentration of CNC to form a continuous solid film having a controlled microstructure, and processing the solid film to form the one or more microdevices on the substrate.
A patent is an intellectual property right granted by the Government of the United States of America to an inventor “to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States” for a limited time in exchange for public disclosure of the invention when the patent is granted.
The United States Patent and Trademark Office (USPTO) is the Federal Agency charged with granting U.S. Patents and registering Federal Trademarks.
Utility patents may be granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or compositions of matter, or any new useful improvement thereof. In general, the term of the patent is 20 years from the filing date.
Design patents may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture. Design patents remain in force for 14 years from the filing date.
Plant patents may be granted to anyone who invents or discovers and asexually reproduces any distinct and new variety of plants. Term of the patent is 20 years from the filing date.
Patent Application - Because there is not a simple form to complete to file a patent, each application is unique, and comprises a number of required forms.
Provisional Application - provides simplified filing with a lower initial cost and one full year to prepare to file a "regular" (non-provisional) patent application. Successful filing establishes an official United States patent application filing date for the invention, permitting the inventor to use the term "patent pending" for one year. There is no such thing as a provisional patent - only a provisional patent application.
To be eligible for a patent, an invention must be:
NEW - not known or used by others in this country or patented or described in a printed publication in this or a foreign country
USEFUL - must have a purpose, and it must operate to perform the intended purpose
UNOBVIOUS - must be sufficiently different from what has been used or described before and not obvious to someone skilled in the art of the technology related to the invention
Process – an act, or a series of acts or steps. See Gottschalk v. Benson, 409 U.S. 63, 70, 175 USPQ 673, 676 (1972) ("A process is a mode of treatment of certain materials to produce a given result. It is an act, or a series of acts, performed upon the subject-matter to be transformed and reduced to a different state or thing." (emphasis added) (quoting Cochrane v. Deener, 94 U.S. 780, 788, 24 L. Ed. 139, 1877 Dec. Comm'r Pat. 242 (1876))); NTP, Inc. v. Research in Motion, Ltd., 418 F.3d 1282, 1316, 75 USPQ2d 1763, 1791 (Fed.
