What is a Standard Essential Patent?
A Standard Essential Patent (SEP) is a patent that is “essential” to a technical standard: meaning it is technically impossible to implement the standard without infringing the patent. SEPs arise when standards-setting organisations (ETSI, IEEE, ITU, 3GPP) incorporate patented technology into a standard. SEP holders gain enormous leverage because every compliant implementer must take a licence; in exchange, SSOs require SEP holders to commit to FRAND (Fair, Reasonable, Non-Discriminatory) licensing as a condition of inclusion.
SEP declaration and validation
- Declaration: patent holders self-declare patents as essential to a standard; declaration is unilateral and not technically validated by SSO.
- Over-declaration risk: roughly 50% of declared SEPs are not actually essential when third-party assessed; creates portfolio bloat and licensing leverage.
- Validation processes: emerging assessor services (Plum, IPlytics, Concur IP) provide technical essentiality assessment for portfolio diligence.
- Royalty stack issue: aggregate SEP royalties across a single product (e.g., smartphone implementing cellular + Wi-Fi + audio codec + video codec) can reach 20-30% of bill of materials if uncapped.
SEP holder strategies
- Direct licensing: case-by-case bilateral negotiation; resource-intensive but high control.
- Patent pools: Avanci (5G), Sisvel, Via LA: aggregate multiple SEP holders into one-stop licensing; reduces transaction costs.
- Portfolio assertion: use SEP litigation threat to drive comprehensive cross-licence deals.
- NPE (Non-Practising Entity) acquisition: sell SEPs to litigation funds for licensing campaigns.
SEPs in Türkiye
Turkish companies are mostly implementers in SEP-intensive markets (smartphone assembly, TVs, white goods, telecom infrastructure). The Turkish Patent and Trademark Office (TÜRKPATENT) does not keep a separate register of SEP status.
Do: conduct technical essentiality assessment on incoming SEP licensing demands; engage with patent pools where rate aggregation creates cost savings; document FRAND negotiation rigorously.
Don’t: ignore SEP licensing demands as implementer: under-licensing exposes to injunction risk and damages multipliers; ignore essentiality validation as licensor: over-asserting harms credibility.
