How Startups Can Save $3,000 on Patent Search

A startup can save $2500 to $3000 per patent on patent search and attorney opinion on its invention if it knows how to use free patent databases to conduct a patent search.

It is well evident that corporate VCs take patents into consideration while funding. To give you an example, 88% of startups funded by Samsung Ventures and 86% funded by Johnson and Johnson have at least one patent in their portfolio.

Similarly many top Silicon Valley VCs like Khosla Ventures and DAG Ventures, for example, have respectively 66% and 59% companies in their portfolio with at least one patent.

Patents, thus, are vital to get financed. The problem, however, is some startups need finance to get a patent. If you file a patent application in the US, for example, you may end up paying $12,000 to $22,000 depending on the complexity of your invention. This includes attorney fee and getting a professional patent search run.

How as a startup you can save some money?

During a patent filing process, you may have to pay $2,500 to $3,000 for getting a professional patent search run with an attorney’s opinion on your invention. This patent search is known as patentability search which is conducted to find out whether an invention is patentable or not.

If something similar is already in existence or if a patent or any other document disclose your invention, it can act as a prior art and can make your invention non-patentable subject matter. Often time, confirming patentability of an invention doesn’t use to be that tough. If an inventor/startup knows how to conduct a patent search using free patent databases, they can confirm this at their own end and can save $2500 to $3000 per patent.
