PulPac’s patent portfolio continues to grow and currently holds 54 families with soon +330 granted patents in 56 countries, covering different aspects of the Dry Molded Fiber technology. All Dry Molded Fiber IP and know-how created by PulPac and its partners, including new findings, are included free in current and new licenses to customers. Not all patent families are publicly available yet, and some are still PCT applications. Altogether, the potential is 1000-1500 granted patents within the following years.
Dry Molded Fiber is a fiber-forming technology invented and licensed by PulPac to packaging manufacturers to replace single-use plastic on a global scale. The technology makes it possible to produce sustainable, fiber-based packaging that is low-carbon, resource-, energy-, and cost-efficient.
“Our process comprises many integral parts that we protect to drive co-development and sharing of innovations. For example, our patent portfolio comprises protection related to types of fiber, mills, and molds, how, when, what, and where to cut a material, and what pressure should be applied”, Peter Ekwall, Chief Intellectual Property Officer, explains.
“To give an example of a typical consideration that often leads to innovations, depending on the product, its density and strength can be important, as well as its esthetics. A targeted density can be achieved in many ways by experimenting with, e.g., type of fiber and pressure. The cost aspect is, of course, also important when choosing the type of fiber and pressure. A pressure above 100MPa gives a high-strength product with a density above 1,2g/cm3”, Ekwall continues.
PulPac gives their customers, the licensees, continuous access to the latest know-how and findings, including patents. Having the direct or indirect protection of patents enables new, transitional technologies to be spread to many recipients, further stimulating innovation and collaboration. The patenting system forces the disclosure of innovations to the world, allowing it to be further developed and providing value to a wider circle of recipients.
