Verified invention-patent certificates with record-level traceability to grant publication and patent numbers.
DBC RESEARCH & INNOVATION · PATENT TECHNOLOGY ASSETS
Turning patent technology assetsinto an early-mover engine for material and product innovation.
54 verified invention grants form a continuous technology cluster from PHA and bio-based polymer systems, aqueous dispersion and interfacial stabilization to paper-fiber pore sealing, continuous film formation and composite barrier structures—supporting new-formulation design, process-window definition and product-concept validation.
00 / INNOVATION OWNERSHIP & CONVERSION
Patent technology assets connect R&D foresight with an engineered path to product innovation.
DBC organizes technology assets around product opportunities. BIOTEN turns polymer, colloid and interface mechanisms into a material platform, while BIOTEN Packaging carries those modules into structural design, coating processes and application validation.

01 / PATENT TECHNOLOGY MAP
Six technology themes connect the engineering chain from dispersion to film formation, barrier and application.
Title-keyword indexing maps grant evidence to polymer systems, aqueous dispersion, interfacial film formation and paper-barrier engineering. The figures express the scale of verified technology assets; selected patents provide traceable technical entry points.
PHA / bio-based polymers
Titles explicitly reference PHA, bio-based polymers, bio-based materials or biodegradable systems.
Waterborne dispersion and film formation
Titles reference aqueous, emulsion, dispersion, suspension or coating systems.
Bio-based × waterborne coupling
Titles match both bio-based and waterborne themes, forming a material-process cross-index.
Paper-fiber interface × barrier structures
21 titles reference paper or fiber; 16 also reference barriers, coatings, emulsions or structural resins.
BIOTEN named ownership
12 invention grant certificates name BIOTEN (Shanghai) Biomaterials as a patent owner.
02 / MECHANISM & PROPERTY AXES
Multiscale film formation and mass-transfer control define the material-engineering evaluation space.
The engineering value of a patent cluster lies in translating polymer chemistry, colloidal stability, paper-fiber interfaces and barrier architecture into observable variables shared across formulation, coating, forming and testing.
Colloidal dispersion stability
Particle-size distribution, interfacial charge or steric stabilization, solids and rheology define the evaluation of storage stability, coating uniformity and film-formation onset.
PARTICLE-SIZE DISTRIBUTION · ζ-POTENTIAL / STERIC STABILIZATION · SOLIDS · RHEOLOGY
Paper-fiber interfacial wetting and pore sealing
Surface energy, dynamic wetting, capillary penetration and pore occupation resolve coating anchorage, pore sealing and defect formation within the fiber network.
SURFACE ENERGY · CONTACT ANGLE · CAPILLARY PENETRATION · PORE SEALING
Continuous film formation and phase morphology
Particle deformation, coalescence, chain interdiffusion and crystallization or phase separation define continuous-film formation, toughness and heat-seal processing windows.
COALESCENCE · CHAIN INTERDIFFUSION · CRYSTALLIZATION · PHASE MORPHOLOGY
Mass-transfer barrier and structural durability
Free volume, interfacial defects, tortuous diffusion paths and multilayer synergy frame the evaluation of water vapor, oxygen, grease and wet-heat durability.
TORTUOSITY · FREE VOLUME · WVTR / OTR · COBB / KIT · FOLDING DURABILITY

These are material and coating engineering evaluation axes, not measured performance claims for a specific product. Project performance must be tied to substrate, coat weight, drying or heat-seal conditions, test methods and measured data.
03 / COLLOIDAL MATERIAL PLATFORM
From PHA aqueous dispersion to self-emulsifying multi-polymer systems.
Selected patents form a chain from PHA nanosuspension and fully bio-based aqueous dispersion to self-emulsifying polyester stabilization and multi-polymer bio-based emulsions, linking particle formation, interfacial stability, component compatibility and continuous-film windows.

05 / EVIDENCE CONTROL
Evidence criteria and technology-asset governance are managed as separate layers.
Grant evidence gate
Only patent certificates enter the grant count; applications, filing receipts, prosecution responses, drafts and working files are excluded.
Identity normalization
Certificate number, patent number, grant publication number, title, printed owner and dates are extracted record by record and deduplicated by patent number.
Technology taxonomy
The 35, 28, 22, 21 and 16 figures are title-keyword classifications. Technology vectors are title-derived engineering mappings and do not replace legal interpretation of claims.
Legal-state boundary
A certificate proves a grant at the evidence cut-off. Current legal effect, annuity status and ownership changes remain subject to the CNIPA patent register.
06 / ENGINEERING CONVERSION
From R&D output to product opportunity: a technology path that is callable, verifiable and convertible.
Grant evidence is translated into project decision parameters: polymer route, dispersion mode, interfacial film formation, barrier architecture and validation method become searchable, combinable and verifiable.
Formulation decisions
Frame candidate systems and risk hypotheses around polymer combinations, emulsification or dispersion routes, particle size and rheological windows.
Application engineering
Integrate paper porosity, surface energy, coating mode, drying profile, folding and heat-seal conditions into interfacial film design.
Property validation
Build substrate- and use-case-specific matrices for Cobb, KIT, WVTR, OTR, adhesion, heat-seal strength and wet-heat durability.
Project evidence
Bind grant numbers, patent titles, technology themes, sample batches, test methods and stage conclusions to strengthen traceability in customer review and technical communication.
A patent grant is not a performance, compliance or scale-up conclusion for any product. These variables define validation work; they do not replace testing or compliance documentation.
Convert the patent technology cluster into an executable material route.
Provide the substrate, structure, coating mode, drying or heat-seal window and target properties so the team can frame formulation hypotheses, interfacial film-formation routes and a barrier-validation matrix.
