The super dynamic nature of these technologies necessitates continuous movement of the R&D wheel, churning out inventions that must be patented. Collectively, these advancements help the wireless industry develop technical standards that are either new, or are revisions of existing standards. Patents are useful, albeit not perfect in some cases, proxy for technological activities and for understanding the state of the art. Patent data serve to verify the novelty, inventive step and industrial applicability of the underlying inventions.<\/p>

Using the international patent classification (IPC) system, we tried to get a sense of where the future of wireless communication is headed in India, and which companies are taking a lead. We focus on technology subclasses that pertain to air interface technologies in wireless communication. More precisely, we extract pending and granted patents in IPC subclasses: H1Q, H03M, H04B, H04H, H04J, H04K, H04L, H04N 01, H04Q and H04W. Technically, these categories are for air interface of new electric elements; new coding; transmission; communication (telephonic, broadcast, multiplex, secret, jamming, telegraphic and pictorial); and network switching. The brief analysis presented below shows trend of patent applications and patent grants in India in the period between February 2015 and February 2017.<\/p>

The first insight is the staggering number of foreign companies applying for patent protection for these technologies in India. Ericsson has applied for the maximum number of patents in India in the past two years, and almost 80% of the patents were in the transmission of digital and wireless communication networks sectors. Tata Consultancy Services is the only Indian company that was able to break into the top tier, focusing mostly on technologies that enable transmission of digital information. Siemens, on the other hand, holds the maximum number of granted patents in wireless communication in India.<\/p>

It is important to understand the trajectory of evolution of air interface\/ wireless communication technologies. It not only gives us a sense of what is on the radar of innovative companies and where is their valuable R&D being channeled, but also how clearly we can see the future of these technologies, IoT for instance, becoming a reality. The second, not unexpected, insight is that majority (almost three-quarters) of granted patents are in the field of transmission of digital information.<\/p>

According to data we analyzed, most patent applications in India are in transmission of digital information. A little over 60% of total applications have been in this field. The focus is overwhelmingly on the IPC subclass H04L. This covers transmission of signals having been supplied in digital form and includes methods for monitoring these. So what does it mean for devices we use everyday? It means that most inventions are in enhanced ability of devices to detect or prevent errors in information or data received; ability of devices to use multiple transmission paths; to make communication more secure; ability of devices to interconnect and switch between processors; enhanced capability of circuits transmitting\/ receiving Morse code; improved systems of baseband and modulated carriers. None of the top 10 companies in the list of granted patents are from India, but they are trying to catch-up. TCS has 35 pending patent applications, with 80% in the digital information (H04L) field. Barring couple of individual inventors, Mahindra Comviva and Wipro have a handful of patents in the pipeline. Samsung\u2019s R&D unit in Bangalore has one solitary patent granted in (no surprises) the pictorial communication category.<\/p>
