Lawrence Livermore National Security, LLC (Livermore, CA)

This disclosure is related to a DLP (digital light projector) system that includes both the first and second source of light. The first source of light may generate a first beam at an initial wavelength, which triggers the polymerization of a resist that is photopolymerizable. The second source of light could generate a second beam at another wavelength that is different from the first wavelength, and in which case the second beam inhibits polymerization of the photopolymerizable resistance. The digital micromirror device a DMD (digital micromirror device) with several micromirrors. It is made to emit light of both the first and the second wavelengths, and create a pattern across the micromirrors. The first image of light causes polymerization of the initial portion of the photopolymerizable resistance, and the second one blocks the polymerization process of a second section of the photopolymerizable resist.

How to Search for Patents

  • Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
  • Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
  • Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.

To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
