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.
In Nortel's recent bankrupcy, the liquidation of the IP assets led to a bidding war. Google offered $900M for the patents; Apple and Microsoft created an alliance (with RIM, Sony, EMC, Ericsson) to offer $4.5B for the same patents^. Certainly there was a great disparity in these bid prices. How can you objectively determine the value of a portfolio and patent duration. Let the tools at IPstreet.com help you.

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).
Proper organization of a patent porfolio is essential to be prepared to properly navigate the IP landscape. One key issue is related to inventorship. Consider the Pfizer patent, patent # 5,760,06^, which is commonly known as the COX-2 inhibitor. Pfizer is currently in a $1B lawsuit because Searle, the original owner of the patent, failed to include a key inventor on the patent. Pfizer inherited this mess when they acquired Pharmacia, who had previously acquired Monsanto, who had previously acquired Searle. Ignorance is not a defensible excuse in patent litigation.
