Foundational inventions

More than 1,400 later patents build on this work.

Forrest P. Gauthier ranks in the top 0.1% of inventors worldwide for the relevance and influence of his work. Most inventors never have a patent that reaches 100 citations. Eight of his exceed it.

Here is why that matters. Every later patent must cite the earlier inventions it depends on, so forward citations are the patent system's permanent record of who got there first. The Gauthier portfolio has been cited more than 1,400 times by later patents in printing, software, imaging, medical devices and diving.

The average United States patent is cited about ten times in its life. Fewer than one in a thousand is cited 100 times. Eight patents in this portfolio have passed 100, and the most cited stands at 160.

That is the signature of a foundational invention. An incremental improvement is cited a few times and forgotten; a foundational one is cited for decades, because the field cannot be worked without building on it. Gauthier's 1995 architecture for data driven marketing became the starting point an entire industry had to license and build upon, and the same pattern is now beginning in the life support patents.

The company

A licensing house built around a working laboratory.

Most patent licensing companies acquire portfolios. Tesseron generates its own.

Tesseron was formed in 2000 when General Electric acquired the product and production operations of Varis Corporation, the company Forrest Gauthier had founded in Mason, Ohio, and Gauthier retained the intellectual property. Tesseron took stewardship of a family of inventions that had already reshaped high-speed digital printing and turned them into one of the most extensively licensed portfolios in the industry. The same engineering discipline that produced those patents never stopped: today Tesseron runs continuous development programs across multiple fields, files new applications every year, and brings the resulting technology to market through licensed operating companies.

The model is simple. Identify a hard problem that an entire industry has stepped around. Solve it at the fundamental level. Secure the intellectual property. Then license it broadly so the solution becomes the standard.

Fields of practice

One inventor. Eight fields. A single method.

Tesseron's work does not respect industry boundaries. The problems change; the approach of first-principles engineering, rigorous prototyping and defensible intellectual property does not.

Digital Marketing

Variable data architectures that mine databases, then merge personalized content into print or digital publications and web pages.

Database miningVDPPersonalization

Document Security

Non-impact E-13B magnetic encoding and the digital encoding methods behind secure documents, travelers checks and debit cards. Gauthier authored the draft ISO specification for non-impact E-13B and was principal in its global adoption.

E-13BISO specificationSecure documents

High-Speed Color Inkjet

The invention that made true CMYK inkjet possible at production speed. By synchronizing the piezoelectric clock sources driving separate printheads, four color channels fire in exact registration instead of drifting apart, so full color can be printed in a single high-speed pass.

CMYK registrationPiezo driveClock recovery

System Reliability

Run-time diagnostic architecture that lets a production system find and report its own faults while it is running, so an operator learns what failed and why instead of watching the line simply stop.

Life Support & Diving Systems

Fully closed circuit rebreathers automated to the point that recreational divers can use them safely, with self-calibrating oxygen sensing, disposable cartridges and intelligent supply valves.

Optics & Augmented Reality

Sports masks that fuse snorkel and SCUBA function with underwater cameras and a heads-up display for precision three-dimensional navigation where GPS does not reach.

Licensing programs

The patents behind data driven marketing.

In 1995, Forrest Gauthier invented and filed the patents that made high-volume data driven marketing practical: mine scattered databases, connect the dots until a real person comes into focus, and put a relevant offer in front of that person at the moment they are most likely to buy.

That invention, and the family of continuations, raster processing and image registration patents that followed it, became foundational to the digital press industry. More than twenty patents issued from the Varis program alone. Tesseron's licensing program brought these patents to the world's largest press manufacturers, software companies and print service providers, through negotiated license agreements and, where necessary, enforcement in United States federal courts.

A second family of inventions solved a different problem, and its consequences were just as large. An inkjet printhead fires from a piezoelectric crystal, and every crystal runs on its own clock. Put four heads in a row for cyan, magenta, yellow and black, and those clocks drift apart within seconds. At production speed the colors land out of register and the image falls apart, which is why early industrial inkjet was effectively monochrome.

Gauthier's solution was to embed timing in the data itself and derive a common clock at every head, so an array of independent printheads behaves as one instrument. That is the invention that made true CMYK inkjet possible at speed, and it is the genesis of the high-speed color inkjet presses now used across commercial printing. The family covers synchronizing piezoelectric clock sources, generating a common stroke frequency across a plurality of printheads, and synchronizing pixel deposition frequencies between print engines.

Beginning in 2014, the enforcement phase of the program was carried out with Industrial Print Technologies LLC, consolidating actions covering two patent families: variable data printing and inkjet printhead synchronization. Tesseron manages the resulting sublicenses and continues to administer its agreements today.

The program established the operating pattern Tesseron still follows: invent at the fundamental level, hold the intellectual property, and license it widely enough that the solution becomes the industry norm.

What Tesseron is building now.

The current program is anchored in the water, where breathing, seeing, navigating and staying healthy are still unsolved engineering problems at consumer scale. Three foundational patents have issued since 2023, four more applications are pending at the patent office, and six were filed in August 2026. The work is commercialized through Blue71 Global under the Pneuma name.

The inventor

Thirty years of seeing what is missing.

Forrest P. Gauthier is the named inventor on every patent family Tesseron manages: 53 patents worldwide with over 600 claims, plus ten pending applications covering target marketing, document security, inkjet printing, system reliability, life support, optics, and medical devices, with innovations commercialized in hundreds of products.

Trained as an aerospace engineer (Northrop University, summa cum laude, with a Master of Science in Technology Management and postgraduate work at Leiden University), he began at General Electric International Operations in Europe and at CFM International, where he helped develop the initial programs for the CFM56 turbofan, still the world's best-selling commercial jet engine.

He then built and sold a succession of technology companies: Response Financial, whose secure X.25 interbank switch went to Mercantile Bank; Anser Technology, where he authored the draft ISO specification for non-impact E-13B magnetic encoding before the company was sold to Bell Canada; Bridge International, a high-volume contract manufacturer in Korea, China and the Philippines sold to the Doosan Group; and Varis Corporation, backed by General Electric, where more than twenty patents issued and Merrill Lynch noted a "dominant technology lead" before GE acquired the operations in 2000. Tesseron was founded on the intellectual property he retained.

His work in diving is first-hand. A diver since 1971 with more than 80 certifications, he is an instructor trainer for PADI, SDI, TDI and DAN, authored PADI's technical diving and hyperbaric chamber courses, has dived rebreathers since 1998, and designed the complete controller package for the Reactor recreational rebreather. He is a Fellow of The Explorers Club, a 5,000-hour commercial pilot, a Merchant Marine officer and an Extra Class radio operator, K1FPG.
