The technology industry continues to be a hotbed of patent innovation. Activity is driven by the increasing demand for energy-efficient and environmentally friendly solutions, the need for faster and more reliable switching capabilities, compact form factors, and advancements in optoelectronic technologies, and the growing importance of optoelectronic materials, such as LEDs or OLEDs, and advanced semiconductor devices. In the last three years alone, there have been over 4.1 million patents filed and granted in the technology industry, according to GlobalData’s report on Innovation in technology: light emitting switchesBuy the report here.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

190+ innovations will shape the technology industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the technology industry using innovation intensity models built on over 1.5 million patents, there are 190+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, aural exciters, in-memory computing, and network-on-a-chip are disruptive technologies that are in the early stages of application and should be tracked closely. RAID transmission error detection, projector-camera system, and hyperspectral imaging, and surround sound systems are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are digital image interpolation and distributed RAID drives, which are now well established in the industry.

Innovation S-curve for the technology industry

Light emitting switches is a key innovation area in technology

Light-emitting switches are versatile devices that integrate the functions of a light switch and a light source. They are commonly utilised to provide illumination in dimly lit spaces like closets, hallways, and stairwells. When activated, light emitting switches emit a bright light, which automatically dims or turns off when not in use. These switches are gaining popularity owing to their energy-efficient operation and convenient functionality, offering a practical solution for efficient lighting control.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 70+ companies, spanning technology vendors, established technology companies, and up-and-coming start-ups engaged in the development and application of light emitting switches.

Key players in light emitting switches – a disruptive innovation in the technology industry

‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
