RASIRC Granted Taiwan Patent for Method and Systems for Purifying Hydrogen Peroxide Solutions

Innovative new products that purify and deliver ultra-pure oxidation chemistries

SAN DIEGO, January 6, 2021 ( - RASIRC announced that the Commissioner of the Intellectual Property Office, Ministry of Economic Affairs, Republic of China has granted patent I703087 for Method and Systems for Purifying Hydrogen Peroxide Solutions. The patent is applicable to all hydrogen peroxide products including BRUTE® Peroxide and The Peroxidizer®. This invention applies the purification of the liquid source before evaporation into ultra-pure gases. Additionally, the purification improves the performance and lifetime of the patented membrane vaporizer.

“Hydrogen peroxide vapor is becoming a critical material for low-temperature processing of 3-dimensional and HAR devices as ozone and plasma methods hit their limits,” said RASIRC Chief Technology Officer Dan Alvarez. “This invention aids in our efforts to continuously improve the purity and consistency of our delivered product.”

This news comes as part of the harvest of research ideas developed over the last 15 years at RASIRC. Now moving into commercialization, this string of patents also includes our Taiwanese patent I683923, granted in April 2020, for the generation and delivery of Hydrogen Peroxide and Hydrazine gases. “These patents add to our global intellectual property footprint and are needed to support worldwide leadership in the delivery of chemistry for low-temperature oxide and nitrides,” said RASIRC Founder and CEO Jeffrey Spiegelman.

All things considered, I saw some counsel from "Shark" financial backer Barbara Corcoran a day or two ago which caused me to recoil and I needed to put this out there as an addendum to her recommendation.
