Rambus fined $US3.5M for fraud

Rambus plans to appeal the ruling, which follows the same judge throwing out the final three of 57 infringement charges by the company on Friday. US District Judge Robert E. Payne ruled that Rambus improperly obtained patents on chip designs that were being developed by JEDEC (Joint Electron Device Engineering Council), the semiconductor standardisation group, Rambus said in a statement.

Rambus' Chief Executive Officer, Geoff Tate said in the statement that although he believes Infineon's charges are "completely baseless," rules pertaining to JEDEC "have been shown to be confusing, conflicting, poorly communicated and generally not complied with by other JEDEC members."

Rambus had taken Infineon to court, claiming that Infineon had infringed upon its design patents in manufacturing SDRAM (synchronous dynamic random access memory) and DDR SDRAM (double data-rate SDRAM). Rambus had made deals with other chipmakers, while Infineon, Micron Technology, and South Korea's Hynix Semiconductor have held out on paying royalties to the company.

It really doesn’t get more “gaming laptop” than this.

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
