Since the start of 2025, PulPac’s patent portfolio has expanded significantly and now includes 67 patent families with nearly 400+ granted patents across 58 countries, covering various aspects of the Dry Molded Fiber technology. With many patent families still in early stages, the full potential of the portfolio is projected to reach between 1,000 and 1,500 granted patents in the coming years.

Among the most recent developments, two European patents set to be granted by the EPO are particularly notable. One broadly covers PulPac’s SCALA machine platform, while the other relates to the use of a steel line cutting tool—both reflecting core innovations within PulPac’s proprietary method.

“By strategically expanding IP derived from both our internal R&D and from our key partners, we continuously broaden solution options, unlock new markets, and foster a knowledge-based ecosystem dedicated to replacing single-use plastics with more responsible, fiber-based alternatives,” says Peter Ekwall, Chief Intellectual Property Officer at PulPac. “One example is PA Consulting, whose innovations have contributed to nine of the patent families within the portfolio.”    

PulPac’s patent portfolio spans multiple areas of fiber application manufacturing. At its core is a novel method for creating three-dimensional cellulose products from an air formed web or air formed blanks-using heat and pressure. This foundational IP supports a continuously evolving technology platform—enhanced by new patents, partner innovations, and trade secrets—all shared with licensees. The technology enables the production of fiber-based packaging that is low-carbon, resource-efficient, energy-efficient, and cost-effective.

“We see collaboration as the preferred path forward. Licensees benefit not only from access to our technology but also from the protection and support that comes with being part of the Dry Molded Fiber community. While we always aim to resolve potential external conflicts—such as unauthorized use or infringement—through dialogue, we remain fully prepared to defend the technology and safeguard the investments made by our licensees when necessary,” Ekwall continues.

PulPac recently validated the strength of its intellectual property in two patent cases regarding its originally filed method for Dry Molded Fiber. One case was before the European Patent Office (EPO) and the other before the Swedish Patent Office (PRV). Both confirmed that the claimed inventions are novel and involve an inventive step.
