Patent Sin #2. Redundancy: The Dead-on-Arrival Patent Application

The Horror: Wasting Money on a Patent Application for an Invention That Lacks Novelty

Inventors often submit patent applications assuming their idea is entirely new. However, the number one reason patents get rejected is prior art conflicts. Prior art is any information related to your invention before your filing date made public anywhere in the world.

  • Novelty (Newness): Your invention must be substantially different from anything else known to the public, anywhere.
  • Scope: Prior art includes anything previously patented, written about in a publication, or sold in the open market, even in a foreign country.
  • The Cost: Skipping a professional prior art search (also called a novelty search or patentability search) can lead to costly rejections, wasted R&D, and lost filing fees.

Lack of novelty doesn’t necessarily mean your invention itself is dead on arrival, but it does mean any patent application for it is. Whether you can still make and sell your invention is what a freedom-to-operate patent search looks at, to see if your invention may be infringing on any patent rights in effect in the countries where you want to make and/or sell it.

Actionable Takeaway

Have a professional, thorough prior art search done early. A patent lawyer can identify existing products and determine if your invention is different enough from what already exists to meet the novelty and non-obviousness (see Sin #4) requirements.

The legal horror stories I’ve seen almost always follow the same plot: someone built something valuable and didn’t protect it, or signed something they didn’t understand, or waited until the damage was already done. You don’t have to be in that kind of story.

I help entrepreneurs, creators, and small business owners across the U.S. make smart, legally sound decisions about their IP: patents, trademarks, copyrights, and trade secrets. For Illinois clients, I also handle business formation and transactions.
