Samsung is a multinational conglomerate company headquartered in Seoul, South Korea, which is comprised of a multitude of subsidiaries and affiliated businesses in electronics, ship building, construction and more.

Samsung invested the 2nd-greatest amount of money into research and development of any company worldwide in 2014; it’s $13.4 billion R&D investment that year was slightly edged by Volkswagen’s $13.5 billion R&D investment that year. Those 2014 R&D expenditures were 28 percent greater than Samsung’s 2013 totals and represented 6.4 percent of company sales. After a long succession of product development in personal electronics, including the popular Galaxy Note large-screen smartphone, Samsung has been putting together innovation teams with a greater focus on 3D printing and virtual reality tech.

In the third quarter of 2014, Samsung sold 73.2 million smartphone units globally, grabbing an industry-leading 24.4 percent market share. This is, however, a smaller market share than the 32.1 percent share that the company enjoyed during the same period last year. Speculation that Samsung is interested in buying BlackBerry has been downplayed by both companies in the face of recent meetings between executives of the two corporations. At the 2015 Consumer Electronics Show, Samsung CEO Boo-Keun Yoon announced that Samsung Text Cluster 2-12-15the company will invest $100 million into the developer community for the Internet of Things, which Yoon expects will connect about 90 percent of the company’s products by 2017.

Throughout 2014, Samsung earned the 2nd-largest amount of U.S. patent grants from the U.S. Patent and Trademark Office. Its 4,952 U.S. patents outpaced 3rd-place Canon by nearly 1,000 patents, but greatly trailed IBM’s total of 7,534 U.S. patents. However, one of Samsung’s subsidiaries, Samsung Display Co., also ranked among the IFI Claims Top 50 U.S. Patent Assignee list with 1,511 U.S. patents during 2014. Using Innography’s analytical research tools to look at Samsung inventions over the past few months (represented in the text cluster diagram to the right), we’re seeing a heavy focus on semiconductor and memory devices as well as display units and wireless communications.

This Internet telephone innovation is designed to work with Universal Plug and Play open networking architecture and would enable a person in a networked home to answer a telephone call with their television.


Display Technologies for Multiple Screens and 3D Images 

multiple screensSamsung is a major developer of consumer televisions and other display technologies and its innovations in this field push the envelope in terms of how we interact with our devices. For example, there is some speculation that the Galaxy S6, likely to be unveiled in March, will have a three-sided touch display interface. Technologies for incorporating multiple screens on a single display for displaying contents are featured within U.S. Patent No. 8949894, entitled Apparatus for Providing Multiple Screens and Method of Dynamically Configuring Multiple Screens. The apparatus claimed here contains a receiving unit to receive a service comprised of video, audio and data components, a first module associating a plurality of logical screens with each of the received services, a second module associating each logical screen with a display screen, a third module that configures state information of screen objects and an abstract services module that provides an abstract service which is received for display on a display screen. This system for dynamic screen configuration is designed to improve the use of interactive television applications by enabling content control through multiple screens on a single display. An enhanced liquid crystal display (LCD) screen which can accommodate viewers who may not be situated directly in front of the display is the subject of U.S. Patent No. 8941793, issued under the title Liquid Crystal Display to Increase Side View Visibility. The LCD protected here includes a first substrate, multiple switching elements which are switched by the same signal, different subpixel electrodes connected to each switching element, a second substrate with a common electrode and a liquid crystal layer formed between the first and second substrates so that each of the subpixel electrodes have a specific area ratio to each other. The resulting LCD has higher transmittance and improved visibility so that the side viewing visibility is closer in experience to viewing the LCD screen from the front.

multi-view 3DSamsung is also continuing development on its lineup of 3D televisions, as is evidenced by U.S. Patent No. 8947779, which is titled Apparatus for Displaying a Multi-View 3D Image. The patent protects a 3D image display apparatus which includes an active optical element having different configurations for adjusting the path of light beams defining different perspectives of a single image by refracting light beams in a time sequential manner and a relay optical system that transmits refracted light beams towards a viewer’s pupil, creating multiple perspectives that are observed together by the pupil to give a 3D appearance. This invention is intended to provide a 3D image which is more naturally displayed than a conventional 3D display apparatus which only provides two views of a 3D image using left-eye and right-eye images.



Vehicular Technologies for Humans and Robots 

Samsung has also been developing automotive and related vehicle innovations for a variety of purposes. Improved systems of communication between a mobile terminal and a vehicular head unit for providing infotainment to car passengers is explored within U.S. Patent No. 8954229, titled Method of Dynamically Changing Content Displayed in a Vehicular Head Unit and Mobile Terminal for the Same.
