Amedica Announces Patent Grant for Silicon Nitride and Other Ceramic Materials

SALT LAKE CITY, March 30, 2018 (GLOBE NEWSWIRE) -- Amedica Corporation (Nasdaq:AMDA), an innovative biomaterial company which develops and manufactures silicon nitride as a platform for biomedical applications, is pleased to announce the issuance of a key material and process patent.  US patent 9,925,295 was issued to Amedica March 27, 2018, covering “Ceramic and/or glass materials and related methods.” The patent covers various methods for improving the antibacterial, osteoconductive, and osteoinductive characteristics of silicon nitride and other ceramic materials, particularly to make them more suitable for use in manufacturing a variety of biomedical implants.  Amedica now has 59 US patents and 6 foreign patents.

“This patent reflects the scientific inquiry and accomplishments in which Amedica has invested heavily during the past few years. Other biomaterials usually require surface textural engineering to make them suitable for applications such as spinal fusion. Silicon nitride is unique in having a favorable nanostructure in the “as-fired” state already. Therefore, our focus has been to move beyond surface topography toward engineering the precise surface chemistry of silicon nitride through thermal, chemical, and/or mechanical treatments to achieve a broad-based material platform that has applications throughout the biomedical space. The innovative strength of this patent has attracted several potential developing partnerships with other companies, both in spine and outside. From an intellectual property standpoint, this patent alone contributes to the lasting and refreshed value in Amedica, specifically our scientific knowledge and our ability to modify and control the material toward specific, desired product applications.” said Dr. Sonny Bal, CEO and Chairman at Amedica.
