There are a number of screen cleaners available in the promotional products business. One type of screen cleaner has a construction manufactured according to US Patent # 7,431,983 and is made by the patent holder, Rakupuri Inc. of Japan. In order to publicly distinguish the patented product from others being sold that are imitations, and in violation of the US Patent, a small D symbol no larger than 6 Pt and in a subtle contrasting color appears in some location on the microfiber side of each screen cleaner. Rakupuri also holds the US Trademark 3,407,948 for DigiClean® which is being used by several suppliers without permission. Our intent is to provide a high quality product that is identified as fully compliant with US Patent and Trademark law. The supporting documents are attached below. |
