Apple has applied for a patent for wireless charging of phones
E-Commerce company Amazon CEO Jeff Bezos has applied for a patent for a technology that protects mobile phones if they accidentally fall.
Phones are increasingly getting expensive and come with sensitive features such as touchscreens and video cameras which are prone to damage on falling.
The new patent that Bezos has filed makes use of the airbag technology used in cars.
After several numerous patent wars among mobile phone companies, patents have become both a good source of revenue and means to stay ahead of rivals.
Recently, search engine company Google bought over 1,000 patents from IBM in an attempt to improve its defences against future patent litigations.
Google had said, "But as things stand today, one of a company’s best defenses against this kind of litigation is (ironically) to have a formidable patent portfolio, as this helps maintain your freedom to develop new products and services."
"Google is a relatively young company, and although we have a growing number of patents, many of our competitors have larger portfolios given their longer histories."
Last week, Apple had applied for a technology that makes it possible for iPods to be charged without the use of wires.
The technolgy makes use of induction and if implemented could save space and make it possible for simutaneous charging of many devices.
