Savage, MN-based Hydra-Flex Inc. has announced that the U.S. Patent and Trademark Office issued a favorable decision in its ex parte reexamination of Hydra-Flex’s U.S. Patent No. 8,887,743 for a chemical delivery system and platform. Hydra-Flex is a privately held Minnesota company that commercializes custom solutions concentrated on the science of fluid handling applications worldwide.

“Hydra-Flex is proud of its innovative technology and its intellectual property portfolio,” company president Jaime Harris stated. “I am pleased the Patent Office agreed that our patent was correctly issued.” Hydra-Flex currently holds 11 patents for its technologies.

The ex parte reexamination was a proceeding in which the Patent Office reexamines an issued patent to verify that that subject matter it claims is patentable. The Patent Office also confirmed that all thirteen original claims in the ’743 patent are patentable and allowed an additional new claim that it determined was also patentable.
