Case Study

Fast-Tracking IP Clarity for a
Microplastic-Free Cosmetics Innovation

A European sustainability innovator needed to know before committing to a patent filing whether their bio cellulose powder formulation was already in the prior art. Intelacia delivered a comprehensive state-of-the-art search across 10+ databases.

Project Brief

The Engagement

The client is a European sustainability company on a mission to eliminate microplastics from cosmetics. Their solution is a bio cellulose powder made through microbial fermentation using bacteria to produce a natural, bio-based ingredient that can replace synthetic polymers in pressed and loose powder cosmetics.

Before committing to a patent filing, they needed a clear answer: had this already been done? Intelacia conducted a state-of-the-art search to identify all relevant prior art across patent databases and scientific literature, giving the client the evidence base they needed to move forward with confidence.

The Challenge

Four Clear Questions Before Filing

Microbial cellulose has a long research history in food, medical, and materials science. The client needed to know whether their specific cosmetic application was already covered in existing patents or publications across all dimensions of the invention.

1
Prior Art Uncertainty

Had anyone already patented bio cellulose powder in a cosmetic formulation? An unknown prior art reference could block or significantly narrow the scope of a new filing.

2
Feature-Level Novelty

The invention had four distinct dimensions: the composition, the use of microbial cellulose in powder form, its use in pressed powders such as compacts, and its use in loose powders such as dusting powders. Each needed to be assessed independently.

3
Coverage Breadth

Relevant prior art could exist across patent databases, chemistry journals, biotechnology publications, and cosmetic science literature. A narrow search would leave dangerous gaps in the analysis.

4
Speed

The client needed a quick, reliable answer to keep their product development and commercialisation timeline on track without compromising on search depth or quality.

Our Approach

A Four-Stage State-of-the-Art Search

We ran a structured four-stage search across more than ten patent and non-patent databases, combining keyword strategies with classification and assignee-level searches to ensure complete coverage.

I
Domain Study and Invention Mapping

We mapped the invention across its four key features: the cosmetic composition, microbial cellulose in powder form, pressed powder formats, and loose powder formats. This gave us a precise, claim-level search brief for each distinct aspect of the invention, ensuring nothing was overlooked.

II
Progressive Search Strategy

We started with tight search strings targeting the specific novelty of the invention, then broadened progressively to capture adjacent prior art in bio-based cosmetic ingredients, cellulose derivatives, and fermentation-derived powders ensuring both precision and completeness.

III
Classification-Based Search

We ran structured searches across IPC, CPC, USPC, and ECLA patent classes to catch relevant filings that used different terminology. Classification searches are especially important in cross-disciplinary spaces such as the intersection of biotechnology and personal care where keyword coverage alone can miss key results.

IV
Assignee, Inventor, and Literature Search

We searched known players in sustainable cosmetic ingredients and microbial cellulose, then extended coverage to scientific publications via ScienceDirect, PubMed, ACM, J-STAGE, IEEE, CiteSeerX, and Google Scholar capturing academic prior art that could equally affect patentability.

Results & Impact

A Clear Prior Art Landscape, Delivered on Time

Intelacia delivered a comprehensive state-of-the-art report within the agreed timeframe, giving the client a clear picture of the prior art landscape and a solid, evidence-based foundation for their IP filing decision.

Prior art landscape fully mapped. The client received a tiered report covering primary results those matching most or all key invention features and secondary results covering partial matches. Each primary result included full bibliographic details and relevant excerpts for the IP team to review.
Novelty assessed feature by feature. The four-dimensional search structure gave the client clear visibility into which aspects of the invention were likely novel and which might face scrutiny during examination enabling sharper, more defensible claim drafting decisions.
Filing strategy strengthened. The prior art findings gave the client's patent attorney a concrete starting point, reducing time spent on drafting and materially lowering the risk of office actions on prior art grounds.
Delivered on time. The full search was completed within the agreed 1-to-2-week window, keeping the client's product development and commercialisation timelines fully intact.
Sustainability mission protected. By understanding the IP landscape before filing, the client could move forward with confidence that their microplastic replacement technology had a defensible path to patent protection.
Methodology

Frameworks & Tools Applied

We applied a staged search methodology combining keyword strategies, patent classification mapping, and multi-database coverage across both patent and non-patent literature tailored to the cross-disciplinary nature of bio-based cosmetic formulations.

Framework / ToolHow We Applied It
Domain Study & Invention AnalysisDeveloped a thorough understanding of bio cellulose powder formulations, including microbial cellulose sources such as Acetobacter, Azotobacter, Rhizobium, and Pseudomonas, and their application in pressed and loose cosmetic formats.
Progressive Search Strategy DesignBuilt evolving search strings starting from the specific novelty of the invention, then broadened progressively to capture adjacent prior art across formulation chemistry and personal care.
IPC / CPC / USPC / ECLA Class MappingSupplemented keyword searches with structured classification-based searches across four major patent class systems to ensure no relevant filing was missed by terminology alone.
Assignee and Inventor SearchConducted targeted searches on known players and researchers in sustainable cosmetic ingredients and microbial cellulose to surface assignee-specific prior art portfolios.
Multi-Database Patent CoverageSearched across Derwent Innovation, Questel Orbit, Espacenet, and Google Patents to ensure global patent coverage across all major jurisdictions.
Non-Patent Literature SearchExtended the search to scientific publications via ScienceDirect, PubMed, ACM, J-STAGE, IEEE, CiteSeerX, and Google Scholar to capture academic prior art that could affect patentability.
Primary and Secondary ClassificationShortlisted results were categorised as primary (covering most or all key invention features) and secondary (partial feature match) to give the client a tiered, actionable view of the prior art landscape.
