Eight landmark patent disputes — told as stories. What was at stake, who fought, what the world looked like during the battle, and what changed when it ended.
1876–1893
The Telephone Patent Wars
Alexander Graham Bell vs. the world
At stake —Control of all telephone communication in America
Alexander Graham Bell filed his telephone patent on February 14, 1876 — the same morning Elisha Gray filed a caveat for a similar invention. Bell's application had arrived at the USPTO hours earlier. The patent was granted. The race had been decided by a matter of hours.
What followed was the most litigated patent in American history to that point. Over 600 legal challenges were mounted against Bell's patents. Investors, inventors, and telegraph companies all had reasons to challenge. The Bell Telephone Company fought every case.
The most serious threat came from the Western Union Telegraph Company, which backed inventor Elisha Gray and Thomas Edison (who had his own telephone designs). Western Union had far more capital and resources. Bell's company survived only because of aggressive litigation strategy, deeper examination of the patent record, and the strength of Bell's original filings.
Outcome
Bell Telephone won every significant case. By the time the core patents expired in 1893–1894, Bell's network was so entrenched that no competitor could dislodge it. The company that emerged — eventually AT&T — held a telephone monopoly in America for nearly a century.
Legacy — The Bell case established early doctrine on patent races and the importance of filing date. It also demonstrated that a small company with a strong patent could defeat a much larger competitor — if the patent held up. AT&T's monopoly, built on Bell's 17-year exclusivity, became the model for how patents could create industries.
1895–1911
The Selden Automobile Patent
George Selden vs. Henry Ford
At stake —Royalties on every automobile sold in America
George Selden was a patent attorney and inventor who filed a broad patent on a 'road locomotive' powered by a liquid hydrocarbon engine in 1879. He never built the car. Instead, through careful continuation filings, he kept the application pending in the USPTO for 16 years — waiting for the automobile industry to develop.
When the patent finally issued in 1895, automobiles were becoming commercially viable. Selden licensed his patent to the major manufacturers, who formed the Association of Licensed Automobile Manufacturers (ALAM). Every licensed manufacturer paid Selden 1.25% of every car sale. The ALAM refused to license Ford Motor Company.
Henry Ford refused to pay. He sold cars without a license and fought the lawsuit openly, positioning himself as the scrappy independent inventor fighting a patent monopoly. The PR was effective. Ford's lawyers dug into the technical specifications and discovered a crucial weakness: Selden's patent specified a Brayton-cycle (two-stroke) engine. Ford used an Otto-cycle (four-stroke) engine. The engines were legally distinct.
Outcome
In 1911, the Circuit Court of Appeals ruled in Ford's favor: the Selden patent applied only to cars with Brayton-cycle engines. Since no one made those, the patent was essentially worthless. The ALAM collapsed. Selden had collected approximately $500,000 in royalties before the ruling.
Legacy — The Selden case is a textbook example of a 'submarine patent' — an application kept pending through continuation filings while an industry develops, only to surface and demand royalties. Congress eventually changed patent law to make the patent term run from filing, not grant — partly in response to submarine patent abuses like Selden's.
1906–1917
The Wright Brothers Aviation Patent War
The Wrights vs. Glenn Curtiss — and American aviation paid the price
At stake —Control of powered flight in America
The Wright Brothers received US Patent 821,393 in 1906 for their wing-warping lateral control system. They had solved the core problem of flight — not propulsion, but control — and their patent was deliberately written broadly to cover any three-axis aircraft control method.
Glenn Curtiss, a talented engineer and aviator, developed rival aircraft using ailerons (hinged flaps at wing edges) rather than wing-warping. The Wrights sued, arguing ailerons performed the same function and were equivalent to their claimed control system. Curtiss argued they were mechanically distinct. The courts largely sided with the Wrights.
What followed was a decade of litigation that consumed enormous resources and stifled collaboration. American aircraft manufacturers could barely build planes. When World War I began in 1914, European nations — where the Wright patent had less force and the aviation industry had developed more freely — had far superior air fleets. The US entered the war with almost no military aviation capability.
The US government eventually intervened, pressuring the Wrights and Curtiss to form a cross-licensing pool in 1917. The Wright-Martin Aircraft Corporation and Curtiss Aircraft combined under government direction to enable wartime production. Orville Wright (Wilbur had died in 1912) reportedly accepted the arrangement under protest.
Outcome
The cross-licensing agreement ended the aviation patent war — but a decade of litigation had set American aviation back by years. The Curtiss aircraft designs were ultimately more advanced than the Wrights'. Glenn Curtiss went on to build successful aircraft companies. Orville Wright sold his interest in the Wright Company in 1915.
Legacy — The Wright Brothers case is the most-cited example of how valid patent rights, aggressively enforced, can harm an entire industry and national interests. It helped shape thinking about compulsory licensing, patent pools, and the balance between inventor reward and technology diffusion.
1933–1954
RCA vs Edwin Armstrong — The FM Radio Tragedy
How a corporation destroyed the inventor of FM radio
At stake —The future of radio broadcasting — and one man's life
Edwin Armstrong was one of the greatest inventors in radio history. He invented regenerative feedback (which made long-distance radio practical), the superheterodyne receiver (which is in virtually every radio ever made), and FM radio — a superior technology that delivered clearer, static-free audio.
When Armstrong demonstrated FM radio to David Sarnoff of RCA in 1934, Sarnoff initially seemed enthusiastic. But FM radio threatened RCA's enormous investment in AM broadcasting and its nascent television network. FM, if widely adopted, would make AM obsolete and require expensive rebuilding of all radio infrastructure. Sarnoff decided FM had to be stopped.
RCA began a multi-front campaign. It disputed Armstrong's FM patents, arguing RCA engineers had independently developed FM techniques. It lobbied the FCC successfully to reassign FM frequencies to a new band in 1945, rendering millions of existing FM radios obsolete overnight. It used its industry influence to delay FM broadcasting licenses and equipment approvals. Armstrong fought back, spending millions of dollars and two decades of his life in litigation.
By 1953, Armstrong was financially ruined, his marriage was destroyed, and his cases were still unresolved. On the night of February 1, 1954, Edwin Armstrong left his New York apartment and never came back.
Outcome
Armstrong died by suicide in February 1954. His wife Marion continued the legal fight. In 1967, after a series of settlements, RCA and the remaining defendants paid approximately $10 million — acknowledging the validity of Armstrong's FM patents. He had been right all along.
Legacy — Armstrong's story is the darkest chapter in patent history. It demonstrates how a dominant corporation can use the patent system — not to protect innovation but to destroy it — through endless litigation, regulatory capture, and financial exhaustion. Armstrong received the technical recognition he deserved posthumously; he is widely considered one of the ten most important inventors in radio history.
1976–1991
Polaroid vs Kodak — Instant Photography's Total War
The largest patent judgment in history (at the time)
At stake —The instant photography market and Kodak's entire consumer business
Edwin Land invented instant photography in the late 1940s. Polaroid's camera system — film that developed in minutes without a darkroom — was one of the technological miracles of the postwar era. Land filed dozens of patents covering the chemistry, the camera mechanics, and the film development process.
By the 1970s, instant photography was a billion-dollar market. Eastman Kodak, the world's largest photography company, decided to enter. In 1976, Kodak launched its own instant camera system. Polaroid sued immediately, alleging infringement of 10 patents.
The litigation lasted 14 years. Kodak argued its products used different chemical processes and physical designs. Polaroid argued the core patents were fundamental to any practical instant photography system. The case involved thousands of pages of technical testimony, expert witnesses on both sides, and years of discovery.
Judge Rya Zobel in the District of Massachusetts ruled in Polaroid's favor in 1985. Seven of Polaroid's 10 patents were found valid and infringed. In 1986, Kodak was ordered to stop selling instant cameras and film — stranding 16 million Kodak instant camera owners without film for their cameras.
Outcome
In 1990, Kodak agreed to pay Polaroid $909 million to settle the damages portion of the case — the largest patent judgment in US history at that time. Kodak exited the instant photography market entirely. Polaroid had won completely.
Legacy — The Polaroid case remains a landmark in patent damages calculation and in the power of a focused, high-quality patent portfolio. It also showed how completely a patent victory can restructure a market: Kodak's instant photography business, which had sold millions of cameras, was simply erased.
2001–2006
NTP vs BlackBerry — The Device That Almost Went Dark
A patent holding company nearly shut down the BlackBerry network
At stake —Uninterrupted service for 4 million BlackBerry users, including the US government
Thomas Campana was an engineer and inventor who developed technology for wireless email in the late 1980s. He filed patents covering systems for transmitting email to wireless devices — before BlackBerry existed. After Campana died of cancer in 2004, his company NTP (a patent holding company) continued his legal fight.
NTP sued Research In Motion (RIM), maker of the BlackBerry, in 2001. RIM's BlackBerry was by then the dominant wireless email device, used by millions of business users and government officials — including much of the US executive branch. NTP alleged that BlackBerry's wireless email system infringed its patents.
The legal battle was intense. RIM argued the NTP patents were invalid — prior art from a discontinued system called Telefind predated Campana's work. The USPTO agreed and began reexamination proceedings. But the courts moved faster than the USPTO. A jury found infringement in 2002, and RIM was ordered to pay $23 million. Then the judge threatened an injunction.
An injunction would shut down the entire BlackBerry network. The US Department of Defense and other government agencies filed briefs arguing that shutting down BlackBerry service would create a national security emergency. The pressure was enormous.
Outcome
In March 2006, RIM paid NTP $612.5 million to settle — all claims, all future infringement, complete resolution. NTP's patents were eventually invalidated by the USPTO, but after the settlement had been paid. The BlackBerry never went dark.
Legacy — The NTP case accelerated the mainstreaming of NPE (non-practicing entity) patent litigation and showed that injunction threats against critical infrastructure created enormous leverage. It contributed directly to the lobbying effort that eventually produced the America Invents Act (2011) and its focus on inter partes review as a faster path to challenging patent validity.
2011–2018
Apple vs Samsung — The Smartphone Patent War
The most expensive patent dispute in consumer electronics history
At stake —The look, feel, and features of the modern smartphone
When Samsung launched smartphones running Android in 2009 and 2010, Apple CEO Steve Jobs was furious. He believed Samsung had copied the iPhone's design and software features. In 2011, Apple filed suit in federal court in San Jose, alleging infringement of patents covering the iPhone's rounded corners, the 'bounce-back' scroll effect, pinch-to-zoom, and tap-to-zoom.
Samsung countersued. The litigation spread across nine countries and involved dozens of cases. At its peak, hundreds of lawyers were engaged. Both companies were simultaneously suppliers and competitors: Samsung made chips for the iPhone even as their phones competed for the same customers.
The US trial in 2012 became a media spectacle. Samsung's internal documents showed employees discussing how to make their phones more 'iPhone-like.' Apple's designers testified about years of work on the iPhone's form factor. The jury — finding in two days what lawyers expected would take two weeks — awarded Apple $1.049 billion.
Years of appeals followed. The Federal Circuit reduced the damages. The Supreme Court weighed in (Samsung v. Apple, 2016) on design patent damages, ruling that the entire-profits rule for design patents applied only to the 'article of manufacture' bearing the design — potentially a component rather than the whole phone.
Outcome
The case settled confidentially in 2018, seven years after it began. The specific settlement terms were not disclosed. Neither side declared victory publicly. Samsung continued selling smartphones globally; Apple continued selling iPhones.
Legacy — Apple v. Samsung reshaped design patent law (via the Supreme Court's 2016 ruling on apportionment of design patent damages), triggered enormous investment in patent portfolios by all major smartphone manufacturers, and demonstrated that patent litigation had become a core competitive strategy in consumer electronics.
2012–present
The CRISPR Patent War
Billions of dollars and the future of medicine — who owns gene editing?
At stake —Patent rights over a technology worth potentially trillions of dollars in pharmaceutical applications
In 2012, Jennifer Doudna at UC Berkeley and Emmanuelle Charpentier (then at the University of Vienna) published a landmark paper demonstrating that CRISPR-Cas9 could be programmed to precisely cut DNA in a test tube. They filed a patent application in May 2012.
Feng Zhang at the Broad Institute (MIT and Harvard) had independently developed CRISPR-Cas9 for use in eukaryotic cells — including human cells — which is the commercially critical application. Zhang filed in December 2012, but paid for accelerated examination. His patent was granted in April 2014 — before Berkeley's application.
Berkeley filed an interference proceeding, arguing they had invented first (under the old first-to-invent rules, which applied because their application predated the AIA). The USPTO Patent Trial and Appeal Board ruled in 2017 that Zhang's and Berkeley's inventions were not in interference — they were different enough to both be patentable. Berkeley's patent eventually issued in 2019.
The dispute continued in appeals courts and in the marketplace. Both patent families were licensed to competing pharmaceutical companies. Editas Medicine (founded by Zhang) and Intellia Therapeutics (founded with Berkeley licenses) competed for the same therapeutic markets.
Outcome
The dispute remains partially unresolved as of 2026. Both patent families are in force. The 2020 Nobel Prize in Chemistry went to Doudna and Charpentier — recognizing their scientific contribution to the discovery. Zhang's patents cover the therapeutically critical eukaryotic cell application. Multiple appellate proceedings have further refined the boundaries.
Legacy — The CRISPR patent war is the defining IP dispute of the biotechnology era. It has created enormous uncertainty for companies trying to develop CRISPR-based therapies, illustrated the stakes of academic technology transfer decisions, and demonstrated that two independent inventors can both receive patents on different but related aspects of the same fundamental technology.
