It seems that SoundBite Communications (NASDAQ:SDBT) is cursed. The company delayed its IPO in mid-October because it received a letter from Universal Recovery Systems about alleged patent infringement. Then, last week, SoundBite slashed its offering from 6 million shares to 5.2 million and priced the deal at $8, which was below its initial $12-$14 range. It certainly didn't help that the IPO came out a day after Thursday's plunge in the Dow.

But SoundBite has a sound business. The company delivers on-demand software for so-called automated voice messaging (AVM) services. This allows companies to send large volumes of recorded messages to customers, for purposes including collections, customer care, and marketing pitches.

Because it's on-demand, SoundBite's technology does not require hardware investments or high-priced consultants. It usually only takes a few days to implement the system.

So far, SoundBite has been growing at a healthy clip. For the first half of this year, revenue is up 49% to $18 million. The company even posted net income of $428,000 in Q3. There are more than 200 customers, including big names like AT&T (NYSE:T).

Of course, SoundBite does face competition -- for example, from Avaya. But keep in mind that many of its rivals have traditional software solutions. In fact, SoundBite's on-demand rivals are fairly small at this point.

Interestingly enough, SoundBite is selling at a discounted valuation compared to some of its peers that have recently gone public. The company currently trades at about 2.4 times revenue, which compares with multiples of 7 to 17 for companies like (NASDAQ:SLRY), athenahealth (NASDAQ:ATHN), and Constant Contact (NASDAQ:CTCT).

What about the legal problems? Such things are normal in the tech world, especially in fast-growing sectors. Consider that ShoreTel (NASDAQ:SHOR) received several patent claims before its IPO. But it looks like investors are shrugging it off.

This is not to imply that there is no risk. A legal fight is not cheap -- and it's distracting.  But SoundBite is selling at a fair valuation in light of its growth rate, and it has a strong product offering. So for Foolish investors searching for an IPO, this one is certainly worth a look.
