It was seen that the works of founders of States, law-givers, tyrant-destroyers, and heroes cover
but narrow spaces and endure but for a time; while the work of the inventor, though of less pomp,
is felt everywhere and lasts forever.          - Francis Bacon Preface to a Treatise on Interpreting Nature

So, naturalists observe, a flea
Has smaller fleas that on him prey;
And these have smaller still to bite 'em,
And so proceed ad infinitum.

     -  On Poetry: a Rhapsody     Jonathan Swift

Innovation in a free market is risky.  For example, a utility patent can help to minimize the risk of competition, but is itself a risk.  Investment (from $10,000 to $30,000) in a patent application is wasted if the patent office denies grant of a patent.  And a patent doesn’t even guarantee that we can use, sell, or profit from embodiments of our own inventions, though we can often do so without a patent.  Patent attorney Ronald Aust helped us understand the risk of a utility patent and how to minimize it.

In some ways, a patent is like a land deed.  A deed specifies where someone’s land is; claims of a patent specify where (in the world of useful ideas) someone’s invention is.  Owners of either land or invention can tell others to keep off their property, can sell or rent their property, and can use their property to develop business relationships.  Both land and invention can be inaccessible to the owner if they are enclosed by another’s property.  For example, if you improved someone else's recently patented chair by adding rockers to it, you might need to reach a cross-licensing agreement with that person before you could sell your patented rocking chair.

Unlike a land deed that can convey a high probability of permanent ownership, a patent conveys a moderate probability of time-limited (usually about 17 years) ownership.  A patent is just the patent office’s tentative (though influential) opinion that a patent holder owns intellectual property.  Anyone may, for good reason, challenge that opinion in a federal court.  If the court decides that the patent is invalid or unenforceable, the defending patent owner loses the patent and at least $300,000 in legal expenses.

Not every innovator needs a patent.  If the law would let you sell embodiments of your patented invention, it would often let you sell those same embodiments without having a patent.  A patent is only one means of protecting your share of the market.  Other protective means include persuasive marketing and public relations, an enthusiastic sales force, a strong business network, or high startup costs.  Especially for a fad invention whose popularity will quickly fade, or for an invention that won’t yield enough profit to attract competitors, it might make more sense to skip the patent and go straight to market.

The first step toward obtaining a patent is to show that the invention works (utility patents are granted only for useful inventions).  That can be done explicitly (in an actual reduction to practice) by testing a physical form of the invention, or implicitly (in a constructive reduction to practice) by filing a patent application.

The second step is to enter the lengthy (think at least 2 years) patent application process, usually through one of two doors.  The earlier and tentative entry – a provisional patent application – leads only to protection (for 1 year) of a place in line at the patent office.  This gives an applicant time to save money for the patent process, to study the market, or to decide whether the benefits of a patent will outweigh the costs.  The later and assertive entry – a nonprovisional patent application – may be opened directly or via the tentative entry, and can lead to a patent.  Opening this door by filing a nonprovisional patent application starts a dialog between the applicant and the patent office examiner.  They discuss whether the invention merits a patent, and if so, what the final form of the patented invention will be.  If all goes well, and after the applicant pays several fees, the examiner will allow issue of a commercially valuable patent to the designated owner of the invention.  If the examiner decides instead to deny issue of a patent, appealing the decision or requesting continued examination of the application can still result in a patent.  Keeping the patent for several years requires payment of more fees.

Literature searches performed before filing a patent application decrease the risk of wasting money.  If a patentability search finds that someone else invented your invention first, there is usually no reason to file a patent application.  If a freedom-to-operate search finds that using your own invention will require negotiation of a cross-licensing agreement, you will be able to make a more informed decision about whether to file an application.

While your provisional or nonprovisional patent application pends, you might study the marketability of your invention.  If few people would buy the invention at your selling price, you might decide to cut your losses and abandon the application.

Pending legislation (America Invents Act, H.R. 1249, S. 23) proposes to grant a patent to the first inventor to file a patent application, rather than to the first to invent.  If that Act becomes law, filing a series of provisional applications on inventive increments, as your invention develops, will decrease the risk of losing the race to another inventor.

Thank you, Mr. Aust, for helping us decide whether to patent our inventions.
