Choosing Invention City

The difference between Invention City and other invention companies is the success, depth and unique experiences of the Invention City team along with a business model that's structured to profit with inventors rather than from them. Invention City grew out of WorkTools, Inc., (read about WorkTools here.) We come at this business having been bona fide garage inventors and that's where our hearts remain. These links explain:

Be careful about disclosing proprietary and confidential information to anyone. We hope that your visit is productive. Please visit us often and let us know how we can make things better.

The Reality of Provisional Patent Applications

Posted on November 28, 2022

CAVEAT: I am not a lawyer and this is not legal advice. I'm someone who's looked at 20,000+ inventions, has overseen 200+ US and international patent filings, has filed dozens of PPAs on my own, has been knocked off multiple times, has been through $5,000,000 patent litigation 1X and $2,000,000 patent litigation 2X, and has licensed inventions to Fortune 500 companies.For 99% (or more) of early stage inventions, there's little reason to spend a lot of time or money on a PPA. It's worth doing, but not something to stress about. The main value of the PPA, for early stage ...

As the inventor you may think you know how people will use your product, but you don’t really know until you hand it to people and ask them to use it at home or at work. Cycle testing clip of Kling KONG™.Before any serious company starts shipping it will take steps to ensure the product delivers on its claims. The company needs to protect its brand and knows that long term losses from shipping a bad product will far ...

Why Cannibalism Can Be A Problem For Inventors Seeking Licensing Deals

Posted on September 19, 2022

I'm not talking about eating executives who say "no" to you, as tempting as that may be. I'm referring to the possibility that sales of your wonderful new invention would replace sales of an existing product. For example, let's say you have a much improved mouse trap that catches mice 100% of the time and costs just pennies more than a conventional mouse trap that fails half the time (we just tried licensing such a product). Why on earth wouldn't a company jump at the chance to license the vastly improved product?Cannibalism. That's why. A company that pretty much owns ...
