Invalidating a us patent
In most jurisdictions, a patent is a right to exclude others from making, using, importing, selling or offering for sale the subject matter defined by the claims when the claim is for a thing (apparatus, composition of matter, system, etc.).
If a claim is for a method, the right to exclude would be to exclude any single party from carrying out all the steps of the claim.
It was then often difficult to decide whether a product infringed a patent, since the sole basis to know the extent of protection was the description, in view of the prior art. However, even among patent legal systems in which the claims are used as the reference to decide the scope of protection conferred by a patent, the way the claims are used may vary substantially.
Traditionally, two types of claiming system exist: No patent system today is a purely either central or peripheral, but the system used in Germany and most of the other countries of continental Europe is considered more central than the system currently used in the United Kingdom, the United States, and especially Japan, which are more peripheral.
The mega-multitouch patent is something called the Steve Jobs patent, and Apple has asserted it in litigation before.

Knowing whether the patent can withstand an attack on validity allows you to take a better-informed and stronger negotiating stance.
In other words, the purpose of the claims is to define which subject-matter is protected by the patent (or sought to be protected by the patent application).
This is termed as the "notice function" of a patent claim—to warn others of what they must not do if they are to avoid infringement liability.
A Patent Validity Search or Patent Invalidity Search is an exhaustive Prior Art Search conducted after patent issuance.
The purpose of the search is either to validate the enforceability of a patent's claims or to invalidate one or more claims of a patent, respectively.
There are many steps inside the USPTO, followed by a potential appeal to the Federal Circuit (and in a few cases even the Supreme Court).
