The flagship treatise · second edition
The Law of Patents, twenty years on.
The second edition of the treatise practitioners have cited for two decades — rewritten for the present, in print as Ali on Patents. The paperback states the law; its companion at aop.onl keeps it current. A treatise you buy once and never outgrow.
What it is
-
The full doctrine of Indian patent law, section by section, with the leading cases synthesised — not merely listed.
-
Twenty years of development folded into a single, current statement of the law.
-
Written to be reasoned from: the treatise a drafter, litigator or judge reaches for.
The digital looseleaf
Print goes out of date; this doesn’t. Every significant case is rendered as a page on aop.onl, and the treatise is backed by a living companion between editions — annual updates, new judgments, corrections. Buy the paperback, own the living law. This is what a looseleaf was always meant to be, without the binder.
How the book and the site work together
The paperback carries the argument; aop.onl carries the updates. A short link in the book opens the current version of any passage; the site’s case pages deepen every citation. One purchase, two forms — page and screen.
Who it’s for
Practitioners and litigators; patent agents past the examination; courts and academics who need doctrine, not just the Act.
