Notpla has a total of 64 patents globally, out of which 34 have been granted. Of these 64 patents, 75% patents are active. United Kingdom is where Notpla has filed the maximum number of patents, followed by United States of America and Europe (EPO). Parallelly, United States of America seems to be the main focused R&D centre and also is the origin country of Notpla.
Notpla was founded in 2014. The company manufactures sustainable packaging solutions designed to eliminate waste and contribute to a healthier planet. Its product portfolio includes plastic-free takeaway food containers, flexible films, paper-based products, edible films, and other naturally derived packaging alternatives. These products are biodegradable without requiring specialist facilities, helping customers reduce plastic waste and lower the carbon footprint associated with packaging.

How Many Patents did Notpla File Every Year?
Are you wondering why there is a drop in patent filing for the last two years? It is because a patent application can take up to 18 months to get published. Certainly, it doesn’t suggest a decrease in the patent filing.
| Year of Patents Filing or Grant | Notpla Applications Filed | Notpla Patents Granted |
| 2025 | 7 | 6 |
| 2024 | 6 | 9 |
| 2023 | 13 | 17 |
| 2022 | 7 | 1 |
| 2021 | 14 | – |
| 2020 | 1 | 1 |
| 2019 | 2 | – |
| 2018 | 12 | – |
| 2017 | 2 | – |
Notpla’s filing trend is not a steady rise. Instead, it shows three clear peaks: 12 applications in 2018, 14 in 2021, and 13 in 2023. The underlying records suggest these peaks correspond to different stages of product development rather than repeated filings around the same technology. The earlier portfolio focused heavily on encapsulating liquids and the machinery used to produce those packages, while later filings expanded into coated packaging, single-use packaging, films, pellets and new packaging formats.
That progression also fits Notpla’s commercial development. The company describes Ooho, its edible liquid bubble, as the technology where it began; it later expanded into takeaway boxes, coatings, paper and flexible films. Notpla’s own company timeline notes the first Ooho machine in 2018, a £10 million Series A in 2020 to accelerate portfolio scale-up, takeaway-box launches in 2022, and Notpla Paper in 2023.
The useful signal is that Notpla’s filing peaks appear to mark changes in the type of problem it was solving. Tracking the portfolio by product platform – Ooho, coatings, rigid packaging, films and manufacturing methods – will provide a much clearer view of its innovation direction than the annual filing count alone.
How many Notpla patents are Alive/Dead?
Worldwide Patents
Notpla has 48 active and 16 inactive patent records, meaning about 75% of the portfolio is still alive. That looks strong, but the more important point is that much of the portfolio is relatively young, with several filing peaks occurring from 2021 onward. This means the current active ratio reflects not just portfolio strength, but also the fact that many newer assets have not yet reached later-stage maintenance or pruning decisions.
The better signal to watch is which older patent families Notpla continues to maintain as newer coating, film and manufacturing technologies enter the portfolio. If early encapsulation families stay active alongside newer material and process patents, it would suggest Notpla still sees value across multiple generations of its technology. If older families begin to lapse while newer ones remain active, that could indicate a shift in where the company sees its strongest commercial opportunity.

Which Notpla Technologies Are Important Enough to Protect Internationally?
Notpla’s patent activity is strongly UK-centred: the UK has 25 publications, while the US and EPO have only six each and most other countries have one or two. The important signal is the gap itself. Notpla is not taking every invention into every major market, which suggests that international protection is being applied selectively rather than automatically.
That makes the foreign-filed families particularly valuable to investigate. If the same coating, film, material formulation, or manufacturing technology repeatedly appears in the US, Europe, and other markets, it may indicate that Notpla sees broader commercial value in that technology. Instead of asking “Where does Notpla file?”, the more actionable question is “Which inventions does Notpla repeatedly choose to protect outside the UK?” Those families could reveal the technologies Notpla considers most important for international expansion.

What Technologies Are Driving Notpla’s Patent Portfolio?
Notpla’s largest technical area is packaging technology (B65D), appearing across roughly 26 publication records, but the portfolio extends substantially into materials science. Polymer and natural-material compositions under C08L appear across about 15 records, while coating technologies under C09D appear across around 12. Paper and coated-board technologies under D21H are also prominent, alongside polymer-processing, film-forming and extrusion classes such as C08J, B29B and B29C.
The important pattern is the combination of these categories. Notpla is not simply patenting the shape of sustainable packaging; it is building IP around the material formulation, barrier coating, film or pellet production process, packaging structure and final product format. That creates a technology chain running from the seaweed-based material itself through manufacturing and ultimately into the packaging customers use.
The areas worth watching most closely are where materials + manufacturing + packaging structure overlap. Those intersections can show which technologies Notpla may be able to transfer across different product lines and therefore where the portfolio has the greatest potential to become a reusable materials platform rather than a collection of individual packaging products.
