A REPORT ON LONG TERM EVOLUTION (LTE)

PATENT PORTFOLIO IN INDIA

INTRODUCTION

IIPRD is an established and well-known Intellectual Property Consulting and Licensing Firm based in

India (Delhi, Bangalore, and Pune) and US, with a diversified yet IP focused business practice

providing services to Global Corporates, Litigation and Prosecution Firms, Licensing Firms, and allied

Entities.

IIPRD conducts various kinds of activities apart from providing services and training to the clients, to

keep ourselves as well others knowledgeable and competitive in the current market scenario. These

kinds of activities also provide insight to the every ongoing process and changes taking place in the

world of technology. IIPRD takes initiative and provides full scale report to readers in different

aspects.

To provide better understanding and scope towards different aspects of patents, IIPRD conducted an

exemplary study on Long Term Evolution (LTE) in India, which is one the fastest growing

technological trend in telecommunication sector. The following paper provides better understanding

about LTE. Let us first understand what led to the study of LTE.

NEED FOR CONDUCTING STUDY ON LTE:

Enforcement of standard-essential patent (SEP) is rapidly increasing in Asia. Recently there was a

case of Ericsson that sued local player Micromax over standard essential patent (SEP) enforcement.

In the case of Swedish based telecom giant Ericsson v/s Micromax, the Delhi High Court ordered

Micromax to pay up to 2 percent revenue earned from the sales of each disputed device to the

court. Ericsson in its litigation filed in the court has claimed that Micromax refused to make a license

pact for patents rights usage regarding wireless technology standard innovations such as 3G, GSM

(Global System Mobile communications) and EDGE (Enhanced Data rates for Global Evolution) and

pressed for a ₹100 crore fine against the company as patent infringement damages. Further, Delhi

High Court also granted permission to Ericsson officials to join the customs department and check

Micromax's devices that are suspected of patent violation. Some of the disputed devices include

Micromax Funbook tablets series, Ninja and Canvas 2 smartphone series.

Micromax rejected the charges saying that "Micromax is committed to negotiating a FRAND (Fair,

Reasonable and Non-discriminatory) license with Ericsson as has Ericsson undertaken to providing a

FRAND license to Micromax. Since the matter is pending before the honorable court, it would be

incorrect for Micromax to make any further statements on the matter."

The interim order from the court is not the result of any FRAND determination by the court but may

merely be based on Ericsson's demands. A deposit (presumably to avoid injunctive relief) is not a

final resolution of a case. The order mentions that products had been held up at customs over

Ericsson's claims and will be released now, and the deposit has the purpose of allowing Micromax to

keep importing and selling. The parties shall negotiate for a month. If they can't agree, the dispute

over royalty rates will be referred to a mediator.

Intellectual property enforcement is critical to the growth prospects of emerging economies,

including foreign companies' IP. India does not have the best reputation so far when it comes to

patent protection. By comparison, China is widely considered to be far more advanced in that field

than India. But for a jurisdiction in which IP enforcement is just developing, SEPs -- which are the

intersection of IP and antitrust laws -- pose a particular challenge. The local players in those

economies generally lack patents to countersue over (Indian companies also file far fewer patents

abroad than, for example, their Chinese counterparts), and probably don't own any wireless SEPs.

Further, Ericsson also accuses Samsung of FRAND violations over LTE or wireless SEPs.

Thus, understanding “what LTE is?” is important and therefore we conducted study on LTE in India.

WHAT IS LTE:

There has always been a promising demand for faster data transmission with unprecedented

penetration of smart phones and tablets in both the developed and developing economies all across

the world. This need has exponentially increased with ever-increasing processor speeds in mobile

devices and expected evolution of cloud computing. Also the Strategy Analytics forecasts that

demand for data traffic will grow by 10-12 times by 2015. Therefore, there is a perpetual

requirement for technologies that support faster transmission. Even though global expansion of 3G

networks continue to drive this decade, upgrade from 3G to 4G is inevitable as need for more

efficient data transmission becomes a necessity.

Long Term Evolution (LTE) is a mobile communication standard for communicating the data with

high speed. The wireless communication standard is marketed as 4G LTE for mobile phones and data

terminals. LTE is based on technologies like EDGE (Enhanced Data Rates for GSM Evolution), UMTS

(Universal Mobile Telecommunications System), and High Speed Packet Access (HSPA) on GSM

(Global System for Mobile Communications) standards. The motto is to increase the speed and

capacity and these features can be further improved by enhancing the features of radio interference

along with core network. LTE standard is developed by 3rd Generation Partnership Project (3GPP),

where it specified in its Release 8 document series and specified the advanced standards in its

Release 9. Although marketed as a 4G wireless service, LTE as specified in the 3GPP Release 8 and 9

document series does not satisfy the technical requirements the 3GPP consortium has adopted for

its new standard generation, and which were originally set forth by the ITU-R organization in its IMT-

Advanced specification. In general, LTE standard addresses the upgrading 3G UMTS to what will

eventually be 4G mobile communications technology. LTE uses evolved UMTS Terrestrial Radio

Access (E-UTRA) as air interface, orthogonal frequency-division multiple access (OFDMA) for

downlink and Single-carrier frequency-division multiple access (SC-FDMA) for uplink to conserve

power. LTE standard supports for Frequency Division Duplex (FDD), Time Division Duplex (TDD)

communication systems and half-duplex FDD with the same radio access technology as well. The LTE

standard can be used with many different frequency bands. As a result, phones from one country

may not work in other countries. Users will need a multi-band capable phone for roaming

internationally.

The structure of LTE is given below in Fig. 1.

ADVANCED LONG TERM EVOLUTION:

LTE-A, a mobile communication standard, is one of the major technologies for 4G standards that has

been set by the Third Generation Partnership Project (3GPP) as a major upgrade from the Long Term

Evolution (LTE) or 3G. The enhancements from the 3G technology are mainly in the form of

increased peak data rates, more spectral efficiency, reduced latency and increased throughput. The

main features that advanced LTE can offer are:

Enhanced data transfer

High spectral efficiency

Better power management

Increased communication reliability

Improved network coverage, deployment, and security

The architecture of Advanced LTE is given below:

Now after understanding LTE, let us formulate the strategy for conducting study on LTE. The

following steps were involved in our study:

1. SEARCHING PATENT DATABASES USING KEYWORDS:

Patent search engines or patent databases are used for searching patents. A key word or phrase that

will theoretically produce a list of all patents is entered in the patent search engine or patent

database that includes that word somewhere within the patent. Plurality of synonyms for LTE and its

related process are entered as keywords, which will produce a list of all essential patents that exist

for the LTE standard. We enclosed set of keywords in Table 1 and results in Table 2 that include both

issued as well as pending patents in India, which might not be essential (SEP) but does relate to the

eNodeB as a product.

The following are the steps involved in patent searching:

Identify keywords

Prepare search string

Run search string in patent database

Extract Indian patents

Analyse patents based on the related product

Categorize based on the technology:

In the research phase, many patents have been identified relating to enodeB-LTE Advanced

technologies and carefully analyzed for categorization into technical domains as represented in the

diagram below:

Fig. 1

Based on the obtained results and patent categories, a graph is prepared indicating company name

along with number of patents it is having related to LTE and eNodeB. The following graph in Fig. 2 is

prepared depicting number of patents belonging to particular assignee relating LTE and eNodeB and

graph in Fig. 3 indicates number of patents belonging to particular category relating to LTE and

eNodeB, however, the graphs might get changed from time to time depending on new published

applications in the particular domain. (List is last updated on 30th of April, 2013).

We were also been able to identify filing trend of patents relating to LTE and eNodeB in India, which

is being depicted in Fig. 3.

Fig. 4 illustrates top assignees who file patent applications in India related to LTE and eNodeB and

number of publications they are having.

And Fig. 5 illustrates top 10 technology categories related to which LTE or eNodeB based patents are

granted and patent applications are being published in India.

Fig. 5

2. NON-PATENT LITERATURE SEARCH

The non-patent literature search is conducted base on analyzing technical publications, blog content

and other online resources for identifying relevant patents and standard essential patents relating to

eNodeB. From our study, the following Indian patent family of corresponding essential patents are

identified based on analysis of patent litigation cases pertaining to eNodeB/LTE-advanced

technology.

3. DETERMINING ESSENTIAL PATENTS

An essential patent means that it is not possible to implement the standard on technical grounds

without infringing on the intellectual property protected by the patent. However, the process under

which this determination is made is a bit convoluted and almost entirely hidden from the public

domain. As such, the simplistic methodologies described earlier in this chapter would fail to capture

the intricacies of how a patent becomes essential.

4. PREPARING STUDY FINDINGS

The study report intends to bring clarity to the patent scope of LTE in India by identifying pending

and granted Indian Patents that directly or indirectly relate to LTE or eNodeB base stations and also

tend to comply with the Release 9 specification. Patents were also briefly assessed to evaluate

whether they would read on eNodeB product that complies with the applicable standards. In

addition, the present report identifies the kind of technology that each patent relates to and

categorizes the patents. A total of 1743 results have been identified and 200 results out of 1743

have reported as part of this study herein in Table 2, which include pending and issued patents in

India. Post the identification of patents using paid and unpaid databases such as Questel Orbit,

Indian Patent Office, USPTO, WIPO, among other databases such as ETSI and reported LTE Litigation

cases, an assessment was made of the kind of patents filed, major players, kind of reporting of SEP’s

in ETSI, among other parameters.

Based on the assessment, a further evaluation was made of prevalent FRAND licensing terms in LTE

domain; particularly for base stations, litigation scenario on FRAND terms, outcome of key

judgements, potential impact of judgements in Asian markets, stands taken by major players during

FRAND and/or LTE litigations, among other attributes.
