A bullet dodged or the bomb-throwing Supreme Court declines  to destroy the patent system… for once. The Supreme Court does not take a patent case unless it can screw up the patent system and make things worse for inventors.  That’s why Your Faithful Correspondent was alarmed when the Court accepted the case of Amgen v Sanofi, which […]

 “There is not a sexual relationship.” … “It depends on what the meaning of ‘is’ is.” President Bill Clinton Ah, the meaning of words, particularly simple words.  Words you thought that you were intimately familiar with, words that you thought you understood.  Words that can damage your presidency or even wreck your patent. Wait.  A simple word can wreck your […]

So, you’ve come up with an invention.  Great!  Now it’s time to apply for your patent.  So how much information must you supply in your patent application?  The general rule is that you must provide ‘enablement’; that is, you must provide enough information in the text and drawings so that a person knowledgeable in the […]

Let’s say the world believes in Unicorns. TikTok is filled with glowing Unicorn affirmation testimonials and whole YouTube channels are dedicated to fuzzy, pixelated videos of Unicorns in the distance.  Learned scientists publish studies speculating about the natural history of Unicorns. You, on the other hand, are part of the small but sturdy band of […]

 ‘Collateral estoppel’ means that when a judge, jury or other tribunal finally decides an issue in litigation between two parties, then the decision controls the same issue between the same parties in subsequent litigation. The losing party can appeal a decision (usually), but once the appeals from the decision are exhausted the issue is decided […]

The USPTO has LOWERED the cost of filing and prosecuting patent applications for small and micro entities.  The USPTO filing fees for small entities (generally, companies with fewer than 500 employees) is now 40% of the filing fee for large entities, down from 50%.  The USPTO fees for micro entities (generally, academics and individual inventors who have […]

It’s time to turn over a bright, shiny new leaf and to make hopeful resolutions with the best of intentions.  Your Faithful Narrator’s thoughts turn to a shiny new beginning of the distant past – to the year 1790, only three years after the Founders hammered out the new U.S. Constitution and one year after […]

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 […]

 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 […]

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! The amount at stake was $2.75 Billion.  That’s Billion, with a ‘B,’ the largest patent infringement judgement in U.S. history.  The parties were Centripetal Networks, Inc., the patent owner, […]
