Although anyone can claim to inventor or create something (e.g., Al Gore created the Internet), the reality is that an idea needs to be carefully considered in context of the law. If you are serious about protecting your invention, you should contact a patent attorney or patent agent. Applying for a patent, and its subsequent patent prosecution process, does cost money. You may see ads for low-cost services to file a patent on your behalf. Such solutions are viable if your goal is to boast to your friends that you patented something. However, if you have real-world business ambitions, it is imperative that the person writing the claims of your patent is a well-qualified lawyer. The adage "you get what you pay for" is very true in the intellectual property community. Realistically, a single patent is going to minimally cost you around $10K for the application fees, legal fees to write the claims, and so on. You want to find a legal professional that is a subject matter expert in your domain (whether it is IT, manufacturing, mechanical engineering, biotech).

Here are five common factors that often determine the worth of an invention. (1) Importance of a Patent: For breakthrough patents, a.k.a. foundational patents, the patents are so innovative that they give the owner a complete monopoly over an entire industry and are extremely valuable, often worth billions of dollars. Although most patents never reach these heady heights they are nevertheless valuable in that they can force a competitor to start innovating to keep pace with new and improved technologies and products in the market. Incremental patents, which make only small advances over existing products, are usually the least valuable though this may not be always so. A question that is often asked in relation to endeavoring to put a price on a patent is 'How much would my competitors pay to use my protected product or process?' (2) The Market: Market size, the number of products that are likely to be made and the cost of each product also have a significant bearing on the value of a patent. What sort of sales can the patent be expected to support, and for how long? A good example of an article which has significant market presence is the ubiquitous Intel chip that is reported to have a value estimated in the billions of dollars. (3) The Patent Term: Patents have a maximum life of 20 years and, therefore, a 20-year potential monopoly. Patents that are just beginning their life and which have longer to run on the their potential monopoly position understandably will have more value. It is rare that a patent nearing the end of its term will cause a great threat to its competitors. It is almost certain that they will have devised technologies or products of their own by then that will not interfere with the patent owners monopoly position. In addition, one has to take into consideration the potential business life of a patent, i.e., the duration, which a patent is likely to be economically useful, if other subsequent patents are providing better alternatives to it. (4) Amount of Prior Art: The number of cited documents or patented products populating an area of innovation also has an effect on the value of a patent. Generally, if the particular product is one of many products of a similar type then the consumers' options de-value the patent of interest, yielding a relatively smaller premium than, for example, a stand alone patent with a captured customer base and no adjacent competition. (5) Patent Significance: Every patent has its own significance in a particular area and will usually form part of an overall IP strategy either to maximize its earning potential or to allow other patents to maximize theirs. Examples of such patents are those that are used to block other key players from gaining a foothold in a market. Yet other examples are those patents that are additional to an original patent and rely on the protected matter in the original patent to successfully operate. It is not uncommon for drug companies or telecom companies to take out further patents protecting a strong first generation of patents, thus securing a big chunk of a market and the ability to negotiate licenses and royalties from the protected, but much desired technology.

In your written patent application you must fully describe your invention to such a degree that a person skilled in the same field as the invention could make or use that invention. A person skilled in the same field as the invention should be able to read your patent application and understand it. The inventor must be able to make claims about his/her invention in clear and definite terms.The part of a patent application that describes and reveals your invention is called the specification and includes various types of descriptions, claims, and drawings depending on the type of invention and type of patent involved. Remember, ideas alone cannot be patented. In other words - you can't just write, "I have an idea for a new alarm clock." You must be able to describe how your alarm works so that an expert in alarm clocks would understand how it would work and that it would indeed work. It's like a recipe ... a good cook should be able to produce your invention based on your patent. As a novice, to file your first patent application yourself is often unwise. However, you could write your own descriptions and then pass them over to your attorney. The attorney could use your writings as a guide and a time-saver, and that will save you money. You should present your inventor's logbook, prototype, and any prior art searches to the attorney. You must write a complete and thorough description of your intellectual property as you cannot add any new information to your patent application once it is filed. You can only make changes to the subject matter that could be reasonably inferred from the original drawings or description.

If the complexities of legalities seems simple, you may want to consider becoming a patent agent or patent attorney. If you are a do-it-yourselfer (DIY), you may want to get David Pressman's book "Patent it Yourself" or David Hitchcock's book "Patent Searching Made Easy". If you are like the rest of us, this process does not seem simple. Sure it may cost some money to engage someone to guide you through this process, so you need to carefully consider your innovation in context of (1) is it patentable? and (2) is it a viable business opportunity? It may, however, be in your best interest to learn as much as you can about the system and then hire a competent patent attorney to get the job done. Just think what it would cost to great idea, poorly patented, which may ultimately cost you "like a bigillion dollars in lost royalties or something like that."
