What is ‘Enablement’ and Why Should an Inventor Care?

December 1, 2022 Patent

Every patent claim must be enabled; that is, the application must have enough information to teach a knowledgeable person how to make and use the invention.  But how much disclosure is enough?  Consider an invention that includes a threaded bolt to hold two objects together.  Infinite variations in the threads are possible, including variations in the shape […]

Reverse Troll

November 10, 2022 Patent

 Some years ago, bashing ‘patent trolls’ was all the rage among the anti-patent community.  Depending on who you asked, a ‘patent troll’ was either (a) a hideous, ugly creature who lurked under bridges and beat innocent passersby with massive patent-shaped cudgels, or (b) anyone who tried to enforce patent rights.  The anti-patent forces got what […]

The Largest Patent Infringement Judgement in U.S. Not a Judgement

October 6, 2022 Patent

Question: When is the Largest Patent Infringement Judgement in U.S. History Not a Judgement? Answer:  When the judge’s wife owns $5,000 worth of stock in the infringer!

Can a State Protect an Invention?

September 15, 2022 Patent

We think of the protection of intellectual property (patents, trademarks, copyrights, trade secrets) as matters of Federal law.  What about the states?  Can, say, Pennsylvania protect an invention by state law independent of the Federal government? The principal impediment to state protection of intellectual property is the Supremacy Clause of the U.S. Constitution: “…This Constitution, and […]

Pub. 2004/0221,355 by Garcia, published November 11, 2004 and shown as fig. 1.  It’s a training aid for competitive swimmers.  The dark patches are weights, up […]

Design Patents – When is an Ornamental Design not Ornamental Enough?

July 7, 2022 Patent

Utility patents protect what things do.  Design patents protect how things look.  Design patents have existed for well over 100 years:  “[w]homever invents any new, original, and ornamental design for an article of manufacture may obtain a patent therefor … .”  So the design patent only applies to an ‘article of manufacture;’ that is, a physical product, and only […]

When Can You Sell Your Invention Without Losing Patent Rights?

June 9, 2022 Patent

You’ve developed a wonderful new product.  The world will soon be your oyster.  But when can you start selling your product?  Can you sell your new product before you file a patent application?   Before the Leahy-Smith America Invents  Act (‘AIA’) became law in 2011, the answer was clear.   OLD LAW: A person shall be […]

When is a Patent Claim ‘Indefinite’ and Why Should We Care?

May 12, 2022 Patent

Patent ‘claims’ appear at the end of a patent and determine what is protected by the patent.  One purpose of the claims is to inform competitors of what they can do without infringing.  Consider the following (entirely bogus) patent claim to an automobile:  An automobile, the automobile having four attractive wheels supporting an optimized frame […]
