This document describes a new computer-aided patent drafting tool called Markush Editor. Markush claims, which cover large numbers of similar chemical structures using generic descriptions, are common in chemistry patents. The Markush Editor allows for automated generation of Markush claims from input chemical structures, interactive editing of the claims, and generation of other patent documents like exemplified structure lists. It aims to save time and reduce errors compared to manual drafting, while also allowing for validation of claims against examples or prior art. Initial customers report saving days of work using the tool.

1. Writing Chemistry patents
Markush Editor - the New Way
Árpád Figyelmesi, Béla Pukánszky

2. Why Markush Claims are important
Between 1994 and 2013
3,704,996 US patents
468,262 with Markush claims
Every eighth patent contains
Markush claims
Markush claims often cover
>1010
structures

R-group editor

9. Safe and convenient editing
● Supports various input formats (SDF, CSV)
● Rich Markush functionality (R-groups, homologies,
position variation, repeating units, multipliers, etc.)
● Easily understandable, informative visualization
● Interactive validation against examples (or prior art)
● Immediate feedback about any inconsistencies or
drawing errors

10. Markush claims drafting
Generate English or Japanese claims

11. Exemplified structures list

12. CONCLUSION

13. Main benefits
A revolutionary new approach of chemistry patent drafting.
● Save time
● Avoid mistakes
● Check any structures against your parents easily
Better quality patents and competitive advantage in protecting your
IP rights.

14. Customers’ voice
“It saves days of work for us!”
(returning statement from several users)
● 15 customers worldwide
● 3 big pharma customers including Bayer
● 5+ ongoing evaluations

15. Ongoing developments
