In reference to the patent: US20170153408

Please let me know what kind of Patent this is,

Design or Utility

& If someone want ed to protect the Look of how a new sunglass's lens looks, would that be a design or utility patent

Thank you

  • Asking if a particular patent is a design or utility patent is a duplicate. If the question were limited to the second question about the sunglass lens, I would be in favor of leaving it open.

US20170153408 is an utility patent application. Utility patents describe a process/method of production of an article/device. Design patents protect the visual/aesthetic appearance of an article. If you're planning on patenting a novel way of making the sunglasses lens you'd need to file an utility patent. In your case I feel you just need to protect the design of your lens hence a Design Patent should suffice.

Hope this helped!

  • You might want to clarify that the linked document is a application and not yet a granted patent.
