The Patent Thicket Literature Review Coding Rules

This collection of terms, definitions, key words have been organized and assigned shorthand codes to identify them. See below:

Core Terms

Saturated Invention Spaces = (SIS)

As first defined by Teece: when a single firm, or a small number of firms, successfully patents an entire technological area. (p.15)
 
Example of:  
imperfect competition - (IC)
Look for:
cluster - (CLSTR)
coherent groups - (CoGs)
adjacent - (Adj)

Diversely-held Complimentary Inputs = (DHCI)

1) products require complementary patented inputs; 2) these inputs are diversely-held (i.e. held by N patent-holders); and 3) patent-holders set their license prices independently. (Shapiro,  pg.17)  

Example of:
coordination - (COOR)
Look for:
diversely-held - (DH)
complementary inputs - (CI)
dispersed - (DIS)
fragmented - (Frag)
Cournot problem - (CP)
multiple marginalization - (MM)

Overlapping Patents - (OP)

Second most common foundation of a thicket.  Vertical overlap is largely adjacent. Horizontal likely due to poorly defined rights.
Refinement patents and research tool patents can result in OP

Example of:
Imperfectly defined property rights - (IDPR)'
Look for:
patent overlap - (PO)
overlapping claims - (OC)
similar claims - (SC)
simultaneous infringement - (SI)

Gaming the Patent System - (GPS)

Patent applicants partake in inappropriate action - such as applying for obvious or non-novel patents.  Puts undue burden on the patent office and crates neg. externalities, such as imposing additional costs on genuine inventors.

Example of:
Moral Hazard - (MH)
Look for:
spurious patents - (SP)
dubious
bad
likely invalid
junk
impeding genuine innovators
rent-seeking
bad faith

Modern Terms

Transaction Costs - (TC)

All fees associated with patenting: applications, prosecution costs, renewal maintenance.  Should de-incentivize low value patents, but may also de-incentivize invention by small firms.

Look for:
prosecution costs
perverse incentive
bargaining costs
coordinating costs
maintenance fees
Leahy-Smith America Invents Act
Coasian

Probabilistic Patents - (PP)

Patents are inherently probabilistic b/c they do not guarantee monopoly rights over new art.  Rather patents suggest a greater likelihood to prevail in court should there be litigation.  They cannot provide perfect protection from infringement or obstruct the filing of invalid patents.  

Look for:
Bessen
Lemley & Shapiro
information asymmetry
uncertainty
invalid patents
infringement
invent around

Unspecified / Extended Use - (UnEx):

Patents issued for reason/utility unknown.  Also applies to patents issued for discreet, inventive steps that do not have stand-alone commercial value.

Look for:
Kiley
ever-greening
Jacob
submarine patents
viagra
expected returns
commercialization opportunities
spurious patents
gaming the patent system
patent portfolios
stand-alone commercial value

Search Costs - (SC)

All costs associated with finding preexisting patents to avoid infringement and verify novelty.  This is particularly expensive for smaller firms lacking robust search capabilities.

Look for:
Wang
Coasian'
perverse incentives
willful infringement

Patent Hold-up - (PH):

The patentees ability to extract higher license fees after the infringer has sunk costs implementing the patented technology.  Had the infringer sought licensing prior to utilization, license fees are assumed to be lower.

Look for:
Epstein
Farrell
Williamson's
rents
royalties
reverse hold-up
guile
FRAND
SEP
Langus
