In the USA, A patent agent is someone who is licensed by the United States Patent and Trademark Office (USPTO) to represent clients in patent proceedings before the USPTO.
Yes and No. Yes, as far as the USPTO is concerned about patent proceedings. No, in that a patent attorney can represent a client outside of a USPTO patent proceeding, such as in trademark proceedings in the USPTO, in an appeal of a USPTO decision to federal court, or in patent litigation.
Licensing of patent agents and attorneys outside the USA may be different, and is not addressed in this FAQ.
Again, yes and no. Patent agents will give legal advice during the drafting and prosecution of a patent application. And this advice can go beyond the representation before the USPTO. The US Supreme Court has held that activities incident to the preparation and prosecution of patent applications, such as advising on the potential patentability of an invention are also permitted. But there is no clear line here, and you may want to discuss some patent-related matters, such as assignments or employer-employee rights, with an attorney (not necessarily a patent attorney) who specializes in the area.
But no, unlike a patent attorney (or any other attorney licensed by the state), a patent agent is not authorized to give legal advice in general.
Yes, you can always represent yourself. The best how-to book is Patent It Yourself, by David Pressman. http://www.amazon.com/Patent-Yourself-David-Pressman/dp/1413305164/
After seeing the complications and pitfalls described, many inventors hire a patent agent.

Yes. Many inventors are not sure who owns their inventions, and suffer from various legal misconceptions about patents. A patent agent can help with those issues as he investigates the patentability of your invention. Patent agents commonly do things like executing a patent assignment and recording it with the US PTO.
Yes. Patent agents sometimes have to, such as under MPEP 708.02, so it is within the skill set and license of someone who practices before the US PTO.
When you get notice of a patent infringement claim, it is usually best to get a competent opinion on whether the patent is valid and whether your product infringes. Otherwise you can be liable for triple damages if a court finds willful infringement.
A patent agent can also handle a reexamination before the US PTO, if prior art shows that a patent's claims should be narrowed or cancelled.
The state of Florida tried to regulate patent agents in 1963, and the US Supreme Court ruled 9-0 that federal law preempts state law, and that patent agents are licensed to practice patent law by the US PTO. No state has tried to regulate patent agents ever since. See Sperry v. Florida, 373 U.S. 379 (1963). http://laws.findlaw.com/us/373/379.html
There is a common misconception that patent agents cannot perform services which the state considers to be practicing law. Eg, see the US PTO's "General Information" pamphlet. http://www.uspto.gov/web/offices/pac/doc/general/attorney.htm
But most of the states define the practice of law in a way that appears to include drafting patent applications, and the US Supreme Court says that patent agents can practice law in that way. There are some people who believe that Sperry v. Florida limits a patent agent to activities incident to the preparation and prosecution of a patent examination, but that is not the position of the USPTO on other activities before the Office, such as reexamination.
The US PTO is currently proposing to revise the ethics rules for patent agents and attorneys, and the new rules continue to keep a single register for agents and attorneys, with all of them equally authorized to practice law before the Office in patent matters. It adds rule 11.102(c) saying that an agent can voluntarily limit his responsibility with a client, if he wishes. http://www.access.gpo.gov/su_docs/fedreg/a031212c.html
Advice is usually privileged and confidential if it reflects a legal question from a client, such as in a patent infringement opinion. Such an opinion would normally only be revealed if the client decided to rely on it at a trial. In almost all jurisdictions, patent agent advice has the same privilege as attorney advice.
In federal court, information is privileged if it is prepared and submitted primarily for the purpose of obtaining legal advice on patentability and legal services in preparing a patent application. See In re Spalding Sports Worldwide, 203 F.3d 800 (Fed. Cir. 2000). http://www.ll.georgetown.edu/federal/judicial/fed/opinions/00opinions/00-m595r.html
You need a lawyer to handle a court case. He does not have to be a patent attorney under the rules.
Possibly, in some states. Currently, none of the 50 states have any statutes or regulations specifically limiting such practices, and no state has successfully brought an action against a patent agent for such a matter since Florida failed before the US Supreme Court in 1963. Some people think that it is possible that some state will try to regulate patent agents, and that some limited regulation might survive legal scrutiny under existing precedents. Others think that such regulation is unlikely or impossible.
As an example of how patent attorneys have (unsuccessfully) tried to limit the practice of patent agents, here is a 1972 NJ advisory opinion from a committee of lawyers. It is doubtful whether these proposed rules are enforceable. http://lawlibrary.rutgers.edu/ethics/cuap/cua9_1.html
To my knowledge, no patent agent in the USA has been successfully prosecuted or punished for practicing patent law.
Many patent agents and attorneys specialize in particular technological areas, so make sure that you hire someone who understands your invention. Beyond that, there are the usual considerations of price, skill, reputation, availability, timeliness, etc.
The US PTO has a list of all the registered patent agents. http://www.uspto.gov/web/offices/dcom/olia/oed/roster/index.html
Patent agents usually just handle patent matters. If you want someone to represent you in a legal dispute, then you probably want a lawyer. If you just want to register a copyright or trademark, the process is relatively simple and you can do it yourself. Nolo Press has some self-help legal books and information. http://www.nolo.com

This Patent Agent FAQ is an attempt to concisely and accurately describe patent agents, without the bias towards patent attorneys that is common on some lawyer sites that have never accepted that 1963 Supreme Court decision. It is not an attempt at consensus among all those who have opinions on the subject. This FAQ will be kept here: http://www.spinstop.com/roger/agentfaq.htm
