What is the best way to determine the correct patent class to file with?

The answer: do both. The first thing you need to know about patents is that the U.S. now has a first-inventor-to-file system after the American Invents Act (AIA) went into effect in 2013. I have to disagree with Dan above: for hardware inventions especially, a patent is an important part of the business plan. The first inventor who "races to the patent office" now is typically the winner. This means if you do not file for a patent on your invention, you can lose the rights to your invention much easier than before the AIA. The next step is to think about how a patent fits into your business plan. A patent application is but a tool in your bag when starting up. A crowdsourcing campaign on a site like Indiegogo can validate the idea. But it also puts the idea out to the public and starts the 1-year clock ticking on when you can get a patent. For hardware startups, however, if you're not thinking about a patent upfront -- you're likely leaving a massive amount of your product's value on the table.

Any suit run by a competent lawyer will ensure that the parties named in the suit include everyone who might be able to pay. So, while your LLC might own some products, it may not be the only entity sued. You might be sued, along with all kinds of other people and companies. I'm not saying there's nothing you can do, but you certainly cannot escape having to defend a suit. Anyone can sue anyone else, even if the suit will ultimately be unsuccessful. You ask how can you handle being sued without going to court? The answer is negotiate a settlement that results in the lawsuit being dropped. So, what have you got to trade? What damage could you do if they continue to sue you, and so on.

First of all, what you have is a provisional patent **application**. For now, the provisional patent application is not publicly available. This can be a big advantage to you. You can use this time to improve your invention and file additional provisional applications. If you don't plan on making/practicing the invention yourself, you should make sure to try to think of everything possible regarding how that invention can be improved. This would (hopefully) come naturally to a practicing inventor. When you file your non-provisional application, your disclosure will be made public ("published") 18 months from the filing of the non-provisional. While your applications are not publicly available, I suggest waiting until you file your non-provisional application(s) to talk to others. Quite often, provisional applications do not have the detail or the scope that the non-provisional will have -- due to the time spent on getting drawings accurate and making sure everything is included in your non-provisional applications. It is best to have a complete application before talking to practicing companies. Sophisticated companies will take advantage of information not disclosed in your provisional application to file their own patent applications. If your applications are not publicly available (or even they are published), you should sign confidentiality agreements (non-disclosure agreements) with anyone you talk to about licensing or buying your invention. Keeping track of who you talked to with confidentiality agreements can be the basis for "notice" of the invention by an infringer -- when they eventually steal your invention. You can sell your idea anytime, but a provisional application is worth a lot less than a non-provisional application which is worth less than an allowed application or issued patent. Provisional applications are generally not as complete as they could be -- and require additional time and finesse to complete the non-provisional application. In terms of appearances, if you are not willing to put in the money to file the non-provisional application, the invention is likely not worth that much money. Companies as well as non-practicing entities may look at provisional applications, but not for long, and will not give you the kind of money that you may get from selling a fully examined patent. Of course, it depends on how good your invention is.

This is a little hard to answer because it is so vague. It depends on the area, the market and the strength of innovation. I know that The App Guy has a terrific podcast at http://www.theappguy.co/ and is also trying to organize a community for App developers to sell their ideas. Let me know if I can be of further assistance to discuss patentability in terms of its value to getting a sale or license. What ever you do, don't spend money filing a full patent, just a provisional. Good luck.

The answer is yes, but it always depends. Let me begin by saying that the more knowhow, etc. involved, the easier it is to sell something without any patent protection. Otherwise, you are trying to sell something without protection and you get no protection until the patent issues, which may take years. The acquirer may just run with it (I would) without licensing knowing there is no cost until your patent issues. Then, when you file, they will see your claims and try to modify their product around your claims. It is slightly vicious in nature. That said, I may not act much different if you file first, unless I can buy your patent or the license costs are very inexpensive. Secondly, many countries have absolute novelty and you will not be able to protect your invention there ever, even if a licensee arises and wants to enter those markets. This too, is a serious limitation for licensing. My conclusion would be that you are underfunded to address your IP and that I can get away with murder. Filing the application is your way of telling people that you are serious. That said, it is not necessary and I have a lot of clients that file later or never file.
