I don't know how well he writes a patent, but I can tell you from looking at his website you need to be aware of this one. He wrote under Provisional patent
" We write a detailed patent specification for you, less claims and background which are not required in a Provisional Application. Drawings and US PTO Filing fees not included."
1. A provisional costs $89 to file so you are paying him $900 to fileout the forms. You can get samples of other provisionals and get an idea of what you need to write.
Look at this response I wrote in the section titled " Hiring Cad Designers"
You know everyone pushes get a patent search done, file a provisional patent, a full patent, do a market analysis, have CAD drawings done. Why? Because you have to pay for these things and they provide a service doing just that.
Here are some things they neglect to tell you.
You can do a patent search yourself using the patent office website or Googles new patent search. The bad thing is if you don't find anything listed it doesn't mean a provisional patent hasn't been filed on it. You just can't see it. You can spend all your money on a patent only to find out somone else has a lock on your spot. Also, you will find out that when you license your idea to a company they may want to improve on your idea or modify it in a way that your patent no longer covers the final product. So another patent has to be filed. Your oringinal patent money was wasted. I have 5 items on the market and didn't spend a dime on the patents. The companies licensing the ideas paid for the patents out of their pockets. The patent covers the product that is being produced.
A provisional patent is cheaper, but starts a 1 year clock. If you don't get it licensed in that year you have to apply for a full patent or your idea becomes public domain and anyone can use it.
Full patents are great if you are a large company and can spend hundreds of thousands of dollars to defend your patent. The average person can not afford to go up against a Disney or Mattel sized company to fight off knockoffs. You will lose any profit you made and be in court for years. If you don't think tha is true look at all the knockoffs of patented items on the shelf right now.
A market analysis is a waste of your money. If you do one today and you find company tolicense your idea they will do their own market analysis and not take your word for it on yours. So, you are paying for something they will do anyway.
You don't need Cad drawings to get a point across. All my drawings are in PowerPoint and two dimensional. I have 5 items on the market licensed and haven't paid to have a drawing done yet.
YOU CAN DO THIS WITHOUT PAYING EVERYONE ELSE AND GOING BROKE.~~
