PLI – PATENT LITIGATION
PLATO, NOMINALISM AND PATENTS
Brad Lyerlawww.marshallip.com
PRINCIPAL CRITICS -- NOMINALISTS
• “Chair” is just a name.• There is nothing that corresponds to “chairness.”
It is just about how language works.• Plato is a realist. He thinks “chairness” really
exists.• Nominalists think “chairness” does not exist; its
just language.• Plato – metaphysics. Nominalists – linguistics.
When we resolve an ambiguity, we have a choice. We can focus on the
invention or we can focus on the words.
INVENTION — ADVANTAGES
● Emphasize Technology.● Claim Scope Co-Extensive
with Invention.● Intuitive to Non-Lawyer
Public.● Legitimacy.
INVENTION — DISADVANTAGES
• Difficult To Do.• May Not Serve Public
Notice Function.• May ignore Johnson & Johnson (disclosed but not claimed subject matter).
WORDS — ADVANTAGES
• Not About Technology.• About a Legal Document.• Public Notice.• Avoid “Reading In”
Limitations.
WORDS — DISADVANTAGES
• Disconnected from theInventor’s Contribution.
• Empowers “Patent Trolls.”• Erodes Credibility of Patents.
INVENTION — HOW ONE BEHAVES
• Wide-Open Process.• All Probative Evidence.• No Bias Favoring Certain
Types of Evidence.
WORDS — HOW ONE BEHAVES
• Tools of a Linguist.• Dictionaries.• Formal Rules of Construction.• Hierarchical. [e.g., UCC § 2-202]
PHILLIPS v. AWH CORPORATION
• Baffles – Only Acute or Oblique Angles in Disclosure.
• Defendant’s Baffles Perpendicular.• Trial Court – No Infringement.• Federal Circuit – Affirmed on Different Analysis.• En Banc – Covers Perpendicular Baffles.• Invention or Words?
PHILLIPS CREATES A HYBRID• Preference for Invention: “The
patent system is based on theproposition that claims cover onlythe invented subject matter.”
• Texas Digital rejected.• Adopts some tools of a Linguist.
Hierarchical Probativity. Claim Differentiation.
WHAT DOES PHILLIPSMEAN BY “INVENTION”
• Not the claims.• The inventor’s contribution to the art.• To discern the contribution, look at the
written disclosure.
CONCLUSIONS
• Rejects ideological purity.• Genius of common law method
to reject ideology in favor of what works.
