What This Patent Covers

This patent protects an electrode catalyst comprising a porous body with a metal core and a nickel-containing oxide skin layer, covering a broad technical scope with 10 claims. Its robust nature, having overcome examiner rejections through multiple amendments, indicates strong validity and a clear technical advantage in the market.

Competitive White Space

The patent focuses on the specific core-skin layer structure of the electrode catalyst. White space exists in developing novel integration methods for these catalysts into diverse electrochemical cell designs or exploring alternative non-Ni oxide skin layer compositions.

estimated ROI · USD · AI analysis
ROI Calculation Logic

Assuming electrode catalyst replacement frequency is reduced from 3 times per year to 1 time per year. If the cost per replacement (including materials and labor) is ~$350K (AI est.), the annual savings from reduced replacements would be (3 - 1) × ~$350K = ~$700K (AI est.). Furthermore, considering a ~30% reduction in manufacturing costs, if annual catalyst procurement is ~$1M (AI est.), an additional ~$300K (AI est.) in savings is expected. The total estimated annual cost reduction is ~$950K (AI est.).

Speed to Market
6× faster than in-house development
Developing a similar high-performance electrode catalyst from scratch in-house would require approximately 3 years for material exploration, structural design, performance evaluation, and durability testing. This technology already features an established porous structure with a core and skin layer, and basic material property evaluations have been completed by the university. This allows licensees to significantly shorten the development period, potentially integrating the technology into existing products or manufacturing prototypes within approximately six months, thereby reducing time-to-market by an estimated 2.5 years.
