Science & IP

The chemistry, on the record.

Our position rests on two things a buyer can verify without asking us: a patent estate covering composition of matter, synthesis and application, and peer-reviewed work published in the open literature.

Patent estate

Protection on composition of matter, synthesis and application.

Every number below is a published international application and can be read in full on Espacenet. Three further applications have been filed and are not yet published; they are counted in the fourteen but not listed.

Solvent polymerisation

3 families

WO2023118407

Reactive phenolic solvent.

WO2023118408

Inert solvent, for example diphenyl ether or dimethoxybenzene.

WO2025003212

Reactive solvent with at least one dimethyl dicarboxylate monomer.

Chain extenders

5 families

WO2024094614

DGO chain extender for oxalic acid copolyesters such as PETO.

WO2024094616

DGO chain extender.

WO2024094621

Metal-free polymer.

WO2024094633

DAO traceless chain extender, where A is a substituted phenol.

WO2024133192

DPC for polyester carbonates.

Chemical upcycling

1 family

WO2023012117

Chemical upcycling of PET and PEF into PEIT and PEIF.

PISOX

2 families

WO2018211133

PISOX diols.

WO2018211132

PISOX diacids.

Patent strategy: protection is sought on composition of matter, on the synthesis technology including composition of matter on chain extenders, and on processing and applications. In collaborations, background IP is filed before work starts and foreground IP rights in key countries are assigned to Parana.

Publications

Fifteen peer-reviewed papers, all open access.

Work on the materials, on their environmental fate, and on what it actually takes to move a biobased material from niche to mainstream. Every paper is free to read.
