Patent Infringement Disputes Between Global Cosmetics Giants and Local Turkish Manufacturers: Under What Circumstances Does Liability Arise?

The cosmetics industry is a highly competitive field where global giants and local manufacturers sit side-by-side, even on the same shelves. Lipstick, foundation, skincare serums, sunscreens, hair care products… Many products may look “similar” from the outside, but behind the scenes, patented formulas, production processes, and packaging technologies .

This situation often brings to the forefront patent infringement disputes , particularly between global foreign cosmetics giants and local Turkish manufacturers . So, under what circumstances does liability arise in a specific case , and to what extent can each party be held responsible?

Below, we examine the critical scenarios and legal frameworks giving rise to liability for patent infringement from the perspective of local manufacturers, brand owners, contract manufacturers, importers, and distributors .

1. Is a Foreign Cosmetics Company's Patent Valid in Türkiye?

The first fundamental question often overlooked in every international dispute is:
"Is this patent valid in Turkey?"

A patent held by a cosmetics giant in the US, EU, or another country does not automatically provide protection in Türkiye. The general framework is as follows:

In order to assert a patent right in Türkiye:
- Having a national patent registration in Turkey ,
- Alternatively, the patent must have been made valid in Turkey through international/regional applications (e.g., via systems like EPC/PCT) .
The mere statement "world-famous brand, world-renowned formula" does not, by itself, guarantee patent protection in Türkiye.

Therefore, in order for a foreign brand to claim "you are infringing my patent" against a local manufacturer, the specific patent must:

Scope,
Its duration,
legal status in Türkiye

This needs to be clarified first. This is also the first point that the local producer should check.

2. Local Producer's Liability for Patent Infringement: Which Actions Are Risky?

In Turkey, which actions by a local manufacturer could be considered patent infringement against a valid patent ?

In general, a patented invention cannot be used without the permission of the patent holder:

To produce,
To use,
To sell or offer for sale,
import,
To possess for these purposes

This could lead to a violation.

Typical risky behaviors in the cosmetics industry:

The strategy involves taking a global brand's patented formula, making minor modifications, producing it in Türkiye, and marketing it under the name "similar product.".
Using patented combinations of active ingredients or specialized carrier systems (for example, special emulsion structures that allow for deeper penetration into the skin) precisely.
To market a product by mimicking a patented dosing pump, airless packaging, or a specialized applicator mechanism.

The critical point here is that in scenarios where the local producer both "own-brand production" and "private label/contract manufacturing ," their area of responsibility as the actor actually implementing the technical solution is very broad.

3. “I’m Just a Contract Manufacturer”: How Does Liability Arise in Contract Manufacturing?

A significant number of local producers outsource manufacturing to other brands . A common defense in this situation is:

"The brand provided the formula, I only produced it; the responsibility lies with them."

From a legal standpoint, the picture is not so simple:

a patented formula or technical solution is produced on the local factory's production line,
The manufacturer is the owner of the act of "producing" the invention protected by the patent .

Therefore:

Together with the brand owner,
The manufacturer may also be held directly liable, not merely passively, for patent infringement .

Factors that can affect the weight of responsibility:

Does the manufacturer have contractual clauses stating that "the customer (brand) guarantees that the formula is not patented"?
Did the manufacturer warn the brand about the technical risks, or was any warning correspondence exchanged?
To what extent did the manufacturer contribute to the design of the formula and packaging?

Such provisions do not legally eliminate liability to the third party (the global patent holder); however, within the internal relationship between the manufacturer and the trademark .

4. Responsibilities of Local Brand Owners and Distributors: Sales, Import and Marketing

In some cases, the local company does not manufacture the product; it only import, distribution, and sales . The defense of "we didn't manufacture it, we only sold it" is not always a valid defense under patent law.

An invention protected by a patent:

importer,
The store,
Distributing to the dealer and retail network,
Marketing on online platforms,

Individuals can also become part of the patent infringement ring.

The following situations are particularly risky:

If the global patent holder informs the local distributor that the product is patented and that an infringement exists, but the distributor continues to sell it.
If a local brand owner is aware of the patent risk of a product manufactured by a contract manufacturer, but aggressively continues marketing it and does not change production despite complaints.
If, despite concrete warnings or past disputes indicating that the imported product is patented in the target market, imports continue with the attitude of "it won't affect us anyway.".

In such cases, importers and distributors may also face serious liability under the category of "knowingly and willingly participating in the violation"

5. The Fine Line Between “Developing a Similar Product” and Patent Infringement

In the cosmetics industry, it's common to develop "similarly effective" products inspired by trending products. However, "similar product" and "copying a patented technical solution" must be carefully maintained.

Risky approach:

The preferred global serum or foundation is sent to the laboratory,
The formula is deciphered as much as possible through chemical analysis
It is presented as a new technology containing the same technical solution with minor modifications.

This scenario, especially if it falls under patent protection, is a classic "reverse engineering and patent infringement" scenario.

A safer approach:

Competing products are examined in terms of market share and impact;
Then, a solution is developed that is technically differentiated based on your own R&D expertise, with different assets, different carrier systems, and different ratios ;
If possible, a "freedom to operate" (FTO) assessment will be conducted for the solution you have developed .

In short, the goal should not be to "do the same thing," but to solve the same problem using different techniques .

6. In Which Cases is the Responsibility of the Local Turkish Producer Considered More Severe?

In practice, the factors that increase the liability of the local manufacturer in patent infringement disputes are as follows:

Continued Violation Despite Clear Warnings
- The global brand sent a cease and desist letter drawing attention to the patent and infringement
- The infringement claim was presented with sample products and technical descriptions
- If the local producer or brand continues production/sales despite this,
  this may be considered "intentional infringement" in court.
Records of Awareness of the Patent
- Even though the relevant patent is mentioned in R&D reports, email correspondence, and meeting minutes, the exact same technical solution is still implemented
- The presence of entries such as, "Let's apply this formula with a minor modification that will surpass X brand's patent.".
Overt Imitative Communication and Marketing Language
- Marketing the product with phrases like "an equivalent to world-renowned brand X," or "offers the same effect at a lower price,"
- The packaging, labeling, and product naming, along with the technical solution, should be designed to clearly target the global brand.

These factors are considered against the local producer, both in determining the infringement and in calculating compensation.

7. Protection Strategies for Local Producers and Brands

Here are some key strategies local cosmetics manufacturers can adopt to avoid competing with global brands and to avoid unnecessary patent risks:

7.1 Pre-Product Development Patent Search

Especially in the "high value-added" segment (anti-aging serums, sunscreens, dermocosmetic products, specialized hair care lines), before developing products:
- The relevant active ingredients,
- The support systems used,
- Special packaging mechanisms

to search patent databases,

An overview of the patent portfolios of prominent global players in this field.

7.2 Risk Sharing Through Contracts

Regarding subcontracting agreements:
- The formula is provided by the brand
- The brand guarantees that the formula will not infringe the rights of third parties .
- In the event of an alleged infringement , indemnity clauses may be added stipulating that the trademark owner will indemnify the manufacturer .
Similar guarantee and responsibility-sharing provisions can also be used in agreements with suppliers and raw material providers.

These provisions do not eliminate liability towards third parties; however, they serve to ensure a fair sharing of the burden of compensation within the domestic relationship

7.3 Legal and Technical Compliance Culture

the R&D team with basic awareness of patent law ,
With the awareness that major global brands are highly likely to use "patented technology" in these areas, more careful formulation is necessary
Prior to a new product launch, ensure that legal and R&D departments conduct a brief joint risk assessment of infringement, at least for high-risk categories .

8. Conclusion: The strongest weapon of local producers against global cosmetic giants is knowledge and strategy

In patent infringement disputes between global foreign cosmetics giants and local Turkish manufacturers , liability is not determined solely by asking "who wrote the formula?".

Whether the patent is valid in Türkiye,
The scope of the local producer's production, sales, and marketing activities,
Contractual framework for contract manufacturing, private label, import and distribution relationships
Whether the violation occurred intentionally or due to negligence

These factors are all considered together.

The healthiest approach for local producers and brands:

To instill awareness of patents and industrial property from the outset in the product development process ,
Supporting subcontracting, supplier and distribution relationships with contractual guarantees ,
It is important not to shy away from seeking technical and legal advice in risky areas .

Thus, a local Turkish producer, in the midst of global competition, can both protect its own innovation and build a legally sound and sustainable growth strategy without unnecessarily conflicting with the legitimate rights of global giants
