NEW YORK (TheStreet) -- An interesting debate is opening up over the actual value of the patents Google (GOOG) - Get Report is getting via its $12.5 billion purchase of Motorola Mobility (MMI) - Get Report.

David Martin, who founded patent consulting firm

M-Kam

and data outsourcing company

Mosaic Technologies

,

recently called those patents "crap"

in an interview on

Bloomberg West

.

According to Martin, Motorola sold off its best patents many years ago to

General Electric

(GE) - Get Report

or spun them off as part of

Freescale Semiconductor

(FSL)

.

Martin adds that many of the Motorola patents that Google bought are dependent on other patents held by Freescale. What's more, he points out that Freescale already has a relationship with

Apple

(AAPL) - Get Report

.

Therefore, there is a good chance that Apple could end up suing Google for the Motorola patents it just bought.

Martin goes on to say that the estate of now-bankrupt

Arthur Andersen

holds a number of significant patents in search that were filed in 1997 -- two years before Google filed any.

Google has been fighting a patent battle on many fronts. There is currently an interesting case winding its way through the court system between Google and

Oracle

(ORCL) - Get Report

. One of the biggest unnoticed bonuses that Oracle acquired as part of

Sun Microsystems

was the Java-related patents.

Oracle is now arguing that Google willfully ignored and failed to license Java patents when it created the Android operating system. It's now suing for compensation.

Apple recently was successful in blocking

Samsung's

Galaxy tablet and phone being sold in Europe, so Google clearly needs to work quickly to address these various patent threats.

What's so interesting about all these patent battles is how ill-equipped we laypeople (i.e., those of us who are not patent lawyers) are at forecasting the likely outcomes.

The recent press coverage of Google's Motorola purchase endlessly mentioned the quantity of patents Google was getting (both issued and pending).

It was impossible for anyone to report on the quality of these patents.

Google will no doubt seek to discredit Martin's expertise in this matter and assure investors it did deep due diligence into these patents.

I've written before that I think the acquisition had more to do with Motorola putting a gun to Google's head by threatening to sue the rest of the Android ecosystem. In a shotgun wedding like this, it seems laughable to claim Google had the time to dig through more than 24,000 patents.

More likely, in my view, is that Google was forced to buy the whole company to avoid something very ugly. It then came up with the spin that it had to do this deal for the patents.

We'll find out in the next year whether Google or Martin is right.
