Usually we would not use the company, because "Sony" is already a proper name and functions like a noun in that phrase, so you don't need another noun. The normal versions would be
if you want to use the name "Sony", or
...from the company.
if you don't want to state the name.
The only time you might use both the name and the company is when
You will have to write to the Consolidated Mutual Company.
This product is made by the Chinese company Pearl River.
This company is made by the Heilongjiang company of China.
because your reader might not know that Pearl River or Heilongjiang are companies.
