An independent research publication.

Arrol Crast is an independent research publication on patents, innovation and technology strategy.

Patents are among the earliest public signals of where engineering organisations are heading. We read them, alongside standards, litigation, licensing deals and technical literature, and explain what they mean for the people who make technology and IP decisions.

All content is drawn from public sources. Commentary is analysis, not legal or investment advice.
