How much will Apple need to pay to Ericsson for a reasonable licensing royalty of 4G LTE patents?

Recently, Ericsson sued Apple for infringement over 41 Ericsson patents including 4G/LTE standard essential patents (SEPs) related to Apple's iPhones and iPads.  Ericsson said Apple owes it patent royalties for using its wireless technologies in the iPhone and iPad, but Apple refused its fair and reasonable licensing offer.

Notwithstanding the recent administrative and judicial blocking against exploiting SEPs for injunction, several courts ruled that SEPs are still eligible for monetary relief for infringement. In Microsoft Co., v. Motorola, Inc., No. 2:10-cv-01823-JLR (W.D. WA), the court provided basic guidelines for assessing FRAND royalty for SEPs. The guidelines are based on the Georgia-Pacific analysis of the reasonable royalty (Georgia-Pacific Corp. v. U.S. Plywood Corp., 318 F. Supp. 1116, 1120 (S.D.N.Y. 1970)) modified for taking into account SSOs’ primary goals for adopting FRAND commitments. The key modification to the Georgia-Pacific factors leads to the reasoning that a royalty in a patent pool for the specific SEPs at issue or comparable licensing transactions as a candidate for the royalty established through negotiation under FRAND commitments. Thus, the royalty rate in the recently formed LTE patent pool may provide expected FRAND licensing revenue.

Another court’s guidelines for assessing FRAND royalty for SEPs can be found in In re INNOVATIO IP VENTURES, LLC, No. 1:11-cv-09308 (N.D. Ill. 2013), Dkt. No. 975. The INNOVATIO IP VENTURES court calculated FRAND royalty (cap) of WiFi SEPs as (average profit margin to the contribution of patentee’s SEPs) x (net profit of relating products) x (pro rata share of patentee’s SEPs to the total number of WiFi SEPs providing similar contribution to the profit). Similar calculation can also lead to the FRAND royalty (cap) for 4G LTE smartphone SEPs.

To evaluate Apple’s 4G LTE smartphone SEPs licensing royalty owed to Ericsson, Ericsson’s IPR share in 4G LTE SEPs is researched. Recent TechIPm, LLC’s research for 4G LTE standard related patent in the US reviles Ericsson’s 4G LTE smartphone SEPs’ IPR share is around 7% (for details about analysis method, please refer to 4G LTE Patents for Standard Innovativeness Ranking: http://techipm-innovationfrontline.blogspot.com/2015/01/4g-lte-patents-for-standard_8.html).

Then, based on various market research data as of 4Q 2014, the net profit of Apple from smartphone sales per year in the US market is calculated as roughly $10 B. Finally, if the average profit margin to the contribution of the 4G LTE SEPs of 3% (smallest scalable product base) is assumed, the licensing royalty of Ericsson that can have from Apple is expected to be around $200 M per year.

To evaluate the innovativeness of patents for 4G LTE standard regarding UE (cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station (eNBs, Femtocells, Relays) products, more than 2000 4G LTE standard related patents that are issued in the USPTO as of Dec. 31, 2014 are reviewed.  TechIPm, LLC’s 4G LTE patents for standard research identified total of 1600 patents that are related to the LTE-Advanced standard.

To evaluate the essentiality of a patent for the LTE-Advanced standard, patent disclosures in claims and detail description for each 4G LTE related patent are compared to the final versions of the 3GPP Release 10 technical specifications for the LTE RAN (Radio Access Network). The evaluated patents are classified according to the level of essentiality that is specified by the Essentiality Index (EI):

E1 : Patent disclosure is weakly related to LTE technical specifications
E2 : Patent disclosure is partially related to LTE technical specifications
E3 : Patent disclosure is related to LTE technical specifications overall
E4 : Patent disclosure is strongly related to LTE technical specifications
To be a potential essential patent candidate, EI should be E3 or E4.

Ranking for the innovativeness of each 4G LTE standard patents assignee is evaluated by the number of patents weighted by the quality factor (EI). Among 35 IPR shareholders, LG is the leader followed by Samsung, Qualcomm, Google (Motorola), Ericsson, Nokia, Apple, InterDigital, BlackBerry, and Panasonic.

NPEs’ IPR share in 4G LTE Standard Essential Patents

TechIPm, LLC’s 4G LTE standard essential patent research for the US market reviles that NPEs’ IPR share accounts for 21% of 4G LTE Standard Essential Patents (SEPs) issued in the USPTO as of October 25, 2013. To evaluate the essentiality of a LTE patent, patent disclosures in claims and detail description for each 4G LTE patent are compared to the final versions of the 3GPP Release 10 technical specifications (LTE-Advanced). Total of 215 issued patents are identified as the potential candidates for 4G LTE SEPs relating to UE (cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station (eNB) products.

Recently, in In re INNOV A TIO IP VENTURES, LLC, No. 1:11-cv-09308 (N.D. Ill. 2013), Dkt. No. 975, the court calculated FRAND royalty of WiFi SEPs: (average profit margin to the contribution of patentee’s SEPs) x (profit margin of relating products) x (pro rata share of patentee’s SEPs to the total number of WiFi SEPs providing similar contribution to the profit). Similar calculation can also lead to the FRAND royalty cap for 4G LTE SEPs. Considering the huge profit margin of 4G LTE UE and base station products in the US market, the amount of licensing royalty earnings generated by NPEs’ 21% IPR share of 4G LTE SEPs will reach billion dollar level.

An essential patent is defined as patent that contain one or more claims that are infringed by the implementation of a specification for standardized technology. Thus, if a LTE product is implemented following the standard specifications, it should infringe some essential patents. To evaluate the essentiality of a LTE patent, patent disclosures in claim and detail description for each LTE patent are compared to the final versions of the 3GPP Release 8 technical specifications.

Total of 152 patents (15 issued patents and 137 published applications) are identified as the potential candidates for LTE RAN essential patent. The LTE IPR shareholders for essential patent candidates are Ericsson, ETRI, Freescale, Huawei, InterDigital, LG, Motorola, NEC, Nokia, Nortel, NSN, Qualcomm, RIM, Samsung, and TI. Among 15 LTE essential patent candidate shareholders, the top 5 IPR shareholders - InterDigital, LG, Nokia, Qualcomm, and Samsung - are appeared as the key member candidates for a successful LTE patent pool formation and operation.

Total of 84 patents are identified as the potential candidates for LTE baseband modem essential IPR and total of 68 patents are identified as the potential candidates for LTE protocol SW essential IPR. Leading in IPR share indicates governance in licensing and a high in profit expectation through licensing royalty. As to the essential IPR share in baseband modem products, Qualcomm is the leader followed by LG, Samsung, Nokia, and InterDigital as of December 31, 2010. As to the essential IPR share in protocol SW products, LG is the leader followed by Qualcomm, InterDigital, Nokia, and Samsung as of December 31, 2010.

The distribution of essential patent candidates among the standard specifications is as follows:
TS36.211 (32%), TS36.212 (7%), TS36.213 (17%), TS36.321 (21%), TS36.322 (6%), TS36.323 (5%), and TS36.331 (12%).

Patents for Cognitive Radio over TVWS 3Q 2010

Cognitive radios are the essential enabler for using a whitespace in TV spectrum bandwidth by finding free spectrum in the TV band. In December 2008, Philips, Samsung, HP, TI, ETRI and GeorgiaTech announced the formation of a new group called the Cognitive Networking
Alliance (CogNeA). CogNeA aims to drive the definition and adoption of an industry-wide standard for low power personal and portable devices to operate over TV White Spaces.

The technologies for the cognitive radios over TV white space are under standardization by IEEE. The technologies for the cognitive radios over TV white space can also be applied to
4G LTE: Femtocell FAP and Self-organizing networks (SONs).

To find the technology innovation status of cognitive radio over TVWS, a keyword search of
the USPTO patent data base has been performed. Total of 701 cognitive radio over TVWS related patents (158 issued patents and 543 published applications) in the US as of Sept. 30 2010 are identified.

Samsung Electronics was the leader in the cognitive radio over TVWS technology innovations followed by Motorola, and Qualcomm.

Qualcomm's LTE Patent Governance

Qualcomm have enjoyed the governance in patents on the Code Division Multiple Access (CDMA) technology it pioneered. As every 3G network uses CDMA technology, Qualcomm was able to license its patents in exchange for a royalty payment that's 4-5% of selling prices on 3G enabled phones.


Recently TechIPm LLC researched LTE patent portfolios for US market leader among LTE UE (cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station (eNB) product manufactures. Total of 1250 LTE patents, issued and published applications in the US as of May 31 2010, are analyzed to find essential patent candidates for LTE RAN (Radio Access Network) standards. To evaluate the essentiality of a LTE patent, patent disclosures in claim and detail description for each LTE patent are compared to the final versions of the 3GPP Release 8 technical specifications.


Total of 72 patents are identified as the potential candidates for LTE baseband modem essential IPR and total of 62 patents are identified as the potential candidates for LTE protocol SW essential IPR. As for the essential IPR share in baseband modem products, Qualcomm (27 %) is the leader followed by Samsung (18%), LG (18%), InterDigital (7%), Nokia (7%), Motorola (6%), and TI (6%) and as for the essential IPR share in protocol SW products, LG (43 %) is the leader followed by InterDigital (19%), Qualcomm (18%), and Nokia (16%) as of May 31 2010.

The top 5 IPR shareholders - InterDigital, LG, Nokia, Qualcomm, and Samsung (total IPR share of 87%) - are appeared as the key member candidates for a successful LTE patent pool formation and operation.


Top 5 LTE essential IP shareholders’ patent portfolios, classified by the key technology components for an implementation of the LTE baseband modem, are compared to excess the innovation competitiveness. Qualcomm’s patent portfolio was distributed among all the key technology components for an implementation of the LTE baseband modem.


Among the total of 134 identified patents as the potential candidates for LTE RAN essential IP only 7 candidates are the issued patents. As the prosecution for the published applications is an ongoing process, it is necessary to watch for a possible IP landscape change. A complete LTE RAN essential IP landscape is expected in two to three years as the current prosecution process for the published and unpublished pending patent applications are finished for a complete set of issued patent data pool.
