Collaborations
Collaboration partners contribute expertise in technical field
WIPO contributes expertise in coordination PLRs and funding
Each collaboration serves as vehicle for partners to familiarize themselves with patent information, analytics, patent system
Collaboration in drafting TOR, delivery phase, evaluation of PLR

WIPO Patent Landscape project
Evaluation after Phase I
Phase II (2012-13)
Budget for 6 further PLRs
Capacity building
Manual for best practices
Regional Workshop for exchange of best practices
Refining standardized tools/procedures of Phase I and developing into future standard service

Ritonavir patent landscape report
Objectives of report:
Identify all patents claiming an invention related to the active ingredient (synthesis, combinations, applications,..)
Analysis of patenting activity
Identify sample innovation tracks, subsequent generations of patents claiming subsequent improvements, new inventions (“evergreening”)
Detailed description of search methodology for pharmaceuticals; suitable as training example

Ritonavir patent landscape report
823 patent families claiming Ritonavir related inventions according to claim language
Many more potentially relevant IP rights in comparison to Orange book of US FDA
To be taken into account in case of technology transfer, local production, procurement through generics: licensing key patent is not enough
Average 13.4 patents per INPADOC family
Largest patenting activity in combination therapies (400 families)
4 sample innovation tracks (liquid and solid dosage forms, synthesis, structural aspects and polymorphs)
1 additional innovation track
Backward citation analysis only revealed patents claiming analogs

Database of Ritonavir related patents
Publication number linked to Espacenet; sortable
Technology categories; sortable

Innovation tracks
Sometimes key inventions take place,
e.g. pharmaceutical substances
Trigger series of further developments
e.g. combinations/formulations, synthesis,....
Starting point of subsequent generations of related patents protecting the further innovation
Such later patents perpetuate protection beyond the 20 years after the filing of the initial patent
I.e. certain technologies using the initial invention may still be protected though protection of first invention may have expired

Orange book: US patents on Ritonavir
![Page 14: WIPO’s Patent services for external users](https://reader036.vdocument.in/reader036/viewer/2022070418/568159a6550346895dc70a73/html5/thumbnails/14.jpg)
Indentification of innovation tracks
Categorizing of patents during retrieval stage
Indentifying most active assignees in particular category
Reviewing documents citing the key patent
Citation map analysis to identify "citation tracks" by exploring backward and forward citations
Claim (granted) analysis to identify
overlap of claim, e.g. confirm similar scope of protection
New aspects of later generation (additional file inspection (via US PAIR))
![Page 15: WIPO’s Patent services for external users](https://reader036.vdocument.in/reader036/viewer/2022070418/568159a6550346895dc70a73/html5/thumbnails/15.jpg)

Innovation tracks explored
Innovation tracks were selected with a view to relevance for generic production in DCs
In initial report:
Liquid oral dosage forms
Synthesis of Ritonavir and key intermediates
Structural considerations and polymorphs
Solid dosage forms
Following later request from DNDI:
Prodrugs of Ritonavir

Search methodology
Report includes extensive description of name search strategies
Names of pharmaceuticals change over phases of drug development
E.g. "Atazanavir", the non proprietary generic name, was assigned at later clinical stage by WHO in 2001 (priority year of founder patent 1995)
Various pre-clinical names
Various chemical naming conventions
CAS registry code CAS-198904313-31-3
Alternatively to Orange Book, founder family can be found by searching for SPCs in INPADOC using Atazanavir since SPC are granted at later stage when generic name is known
3rd alternative to identify founder patent is backward citation analyis.
