I had a product I wanted to patent so I could sell it. I did some research online and found a few similar patents. I wanted a professional search done, to cover all the relevant patents, so I would know exactly what other products in this field had already been patented.
After reading many reviews of other inventor-marketed companies, I contacted inventionhome.com since they seemed the "least bad". They offered me a patent search for $399 to begin the process.
I was aware that most patent attorneys charge around $1000 for a patent search, so I thought I was getting a good deal.
I paid my $399, and within a couple days they sent me an email listing all the patents that matched my idea. To my disappointment, they had only found five relevant patents. With my own search using google patents, I had found seven others by myself, for free. Only one patent was duplicated in both my list and their list.
I was expecting a comprehensive list of patents, not a short list I could have created myself with ten minutes of internet usage.
I told them that I had found other patents, and they said the ones in their list were the most relevant. This was completely untrue, as the patents I had found, that they had missed, were all very similar to the ones they found. In fact, one of the patents that I found, that they did not find, was an expired patent for the same idea. This expired patent placed the product into the public domain, where anyone could now use it.
They missed this very important patent, which makes the whole process of patenting this product useless.
Since they actually provided the service, I am unable to reverse the charges on my credit card. So I paid them $400 for incomplete information. Had I relied on their information alone, I would be filling out a patent application right now, and wasting years in the process, on a product already in the public domain. Their patent search was misleading and incomplete.
They just want people to purchase their assistance in filing patents, it does not matter if the idea has already been patented or is in public domain. Beware.
