According to GlobalData’s company profile on Oji, Incontinence monitoring sensors was a key innovation area identified from patents. Oji's grant share as of February 2024 was 43%. Grant share is based on the ratio of number of grants to total number of patents.

A recently granted patent (Publication Number: US11913172B2) discloses a unique glass plate interleaving paper designed for specific applications. The paper is primarily composed of cellulose pulp, with more than 0 mass % of aluminum sulfate and talc included in its composition. Notably, the paper contains no more than 0.1 mass % of papermaking chemicals, and it completely excludes papermaking surfactants and cationic polymers. Additionally, the glass plate interleaving paper is characterized by its low aluminum ion release (less than 0.01 mass %), talc content below 0.1 mass %, and a basis weight ranging from 10 to 100 g/m2.

This innovative glass plate interleaving paper offers a specialized solution for applications requiring specific characteristics. By incorporating aluminum sulfate and talc while limiting the presence of certain chemicals, the paper ensures minimal aluminum ion release and maintains a specific basis weight range. The exclusion of papermaking surfactants and cationic polymers further distinguishes this paper, making it suitable for unique interleaving requirements in the glass industry. Overall, this patented glass plate interleaving paper presents a tailored option for industries seeking precise interleaving materials with defined composition and performance parameters.
