Apple is becoming more aggressive in protecting its iPod trademark and is now attempting to establish control of the word 'pod' and, in one case, 'podcast'.

Apple has also been consistently resolute in its attempt to control the use of the word 'iPod'.

The company has issued cease and desist orders against the use of the terms 'Podcast Ready' and 'myPodder', insisting their use infringes upon its trademark and confuses its customers.

Podcast Ready owner Russel Holliman believes Apple's attempt to claim control over the word 'podcast' is misconstrued.

While podcasting may have derived some inspiration from the word 'iPod', it has manifested itself as its own industry that is not affiliated with a brand.

Apple has also been pursuing manufacturers of products that use the word 'pod' in their name, even when those goods have no connection with digital audio.

Most recently it slammed Profit Pod and TightPod with demands that the product names be changed.

In the case of TightPod, Apple reportedly paid a manufacturer to rebrand a laptop bag that was marketed under that name.

In the case of Profit Pod, Apple pursued a manufacturer of devices for arcade gambling machines for its use of the expression 'pod' within its fruit machine tracking device.
