Patent Trolls: 5 Tactics And 5 Defense Strategies

Patent trolls represent a shadowy side of the intellectual property landscape, where entities exploit legal protections not for innovation but for profit through litigation. These non-practicing entities (NPEs) acquire patents solely to demand settlements from companies accused of infringement, often without ever producing a product themselves. This practice drains resources from genuine innovators, particularly small businesses, stifling economic growth and creativity.

Defining the Patent Troll Phenomenon

A

patent troll

, also known as a patent assertion entity (PAE) or non-practicing entity, is an organization that holds patents but does not manufacture, sell, or use the inventions they cover. Instead, they aggressively enforce these rights through lawsuits or threats of litigation against companies whose products or services allegedly infringe. The term evokes mythical creatures that lurk under bridges demanding tolls, mirroring how trolls ambush unsuspecting businesses.

Unlike legitimate patent holders who invest in development, trolls focus on extracting licensing fees. They often purchase low-value or broad patents from distressed companies, then scour the market for targets. This model thrives because litigation costs can exceed $1 million per case, pressuring defendants to settle even if claims are weak.

• Broad Patents: Vague claims covering everyday technologies like basic software functions.
• Shell Companies: Anonymous entities hiding true ownership to avoid countersuits.
• Demand Letters: Initial threats seeking quick payouts to avoid court.

Historical Roots and Evolution of Trolling Tactics

The concept traces back to the late 19th century with figures like George Selden, who patented a basic automobile design in 1895 and licensed it to carmakers without building vehicles himself. This early example set a precedent for monetizing patents passively.

Modern trolling surged in the 1990s with software and internet patents. The term ‘patent troll’ gained traction around 1998, coined by Intel’s Peter Detkin to describe aggressive enforcers. By the 2000s, trolls like NTP Inc. targeted giants such as Research In Motion (BlackBerry), securing a $600 million settlement in 2006 over wireless email patents.

Today, trolls adapt by using portfolios of hundreds of patents, filing mass lawsuits in plaintiff-friendly courts like the Eastern District of Texas. They leverage ‘scattered infringement’ suits against multiple defendants to multiply pressure.

Key Milestones in Patent Trolling History

Year	Event	Impact
1895	Selden’s auto patent	Pioneered passive licensing
1998	Term ‘patent troll’ coined	Public awareness rises
2006	NTP vs. RIM settlement	$612M payout highlights risks
2011	America Invents Act	Reforms target abuse

How Patent Trolls Operate: A Step-by-Step Breakdown

Trolls follow a calculated playbook to maximize returns with minimal risk.

1. Acquire Patents: Buy cheap from bankrupt firms or file overly broad applications.
2. Monitor Markets: Scan products, patents, and news for potential infringers using automated tools.
3. Send Demand Letters: Accuse infringement, demand $10K-$500K settlements, threaten injunctions.
4. File Suits: If ignored, sue in favorable venues; often join multiple defendants.
5. Negotiate Settlements: 90%+ cases settle pre-trial due to costs.

Shell companies obscure ownership, preventing countersuits since trolls produce nothing infringing themselves. Hedge funds finance these operations, betting on settlements.

Economic Toll on Businesses and Innovation

Patent trolls cost the U.S. economy $29 billion annually in direct costs, with indirect losses from stifled innovation reaching billions more. Small and mid-sized firms bear 40% of suits despite fewer patents, as they lack defenses of large corporations.

Victims divert funds from R&D to legal fees, delaying product launches. A 2014 study found trolls reduce venture capital and startup activity in targeted tech areas. Consumers face higher prices as costs pass through supply chains.

• Small Businesses: Often settle for 10-20% of revenues to survive.
• Tech Sector: 60% of lawsuits target software makers.
• Global Reach: Increasing in Europe via unitary patents.

Legal Reforms and Their Limited Success

U.S. responses include the 2011 America Invents Act (AIA), introducing inter partes review (IPR) for faster patent invalidation. The 2017 Supreme Court ruling in TC Heartland curbed venue shopping.

Yet trolls persist, shifting to state courts or overseas. Fee-shifting laws in some states award costs to prevailing defendants, deterring frivolous suits. Internationally, WIPO debates balanced enforcement without harming legitimate holders.

Protecting Your Business: Proactive Defense Strategies

Knowledge is the first line of defense. Businesses should:

• Conduct Patent Audits: Review operations against known troll portfolios.
• Insurance: Patent defense policies cover litigation costs.
• Respond Strategically: Ignore baseless letters; challenge via IPR.
• Join Coalitions: Groups like EFF’s troll tracker share intel.
• Build Your Portfolio: Strong patents enable cross-licensing.

Consult IP attorneys early; many offer flat-fee demand letter reviews.

Defense Options Comparison

Strategy	Cost	Effectiveness	Best For
Settlement	Low immediate	Quick resolution	Small claims
IPR Challenge	Medium ($300K+)	High (invalidate patent)	Strong cases
Litigate	High ($1M+)	Variable	Large firms
Insurance	Annual premium	High coverage	All sizes

Case Studies: Lessons from the Trenches

In 2013, Innovation Management Associates targeted 200+ Texas businesses with fax patents, extracting millions before IPR invalidated them. Small retailers settled for $5K-$20K each.

Conversely, Newegg fought back against TQP Development’s online shopping patent, winning via IPR and securing fee awards, deterring future suits. These stories underscore persistence pays.

The Future of Patent Enforcement: Trolls vs. Reform

AI-driven patent analysis may help trolls identify targets faster, but blockchain for provenance could verify originality. Proposed laws like the STRONGER Patents Act aim for balance.

Ultimately, distinguishing trolls from genuine enforcers protects inventors while curbing abuse. Businesses must stay vigilant in this evolving arena.

Frequently Asked Questions (FAQs)

What makes a patent troll different from a legitimate patent holder?

Trolls do not practice their patents (no products/services), focusing chiefly on litigation for revenue, unlike operating companies defending market position.

Can small businesses afford to fight patent trolls?

Yes, via IPR (cheaper than full trial) or insurance; coalitions amplify resources.

Are patent trolls illegal?

No, but reforms target abusive practices; settlements are legal business decisions.

How can I spot a troll demand letter?

Vague claims, high demands relative to evidence, shell company sender, no prior relationship.

What role does the USPTO play?

Issues patents; post-grant reviews allow challenges, but backlog enables weak grants.
