SAN FRANCISCO (Reuters) - Apple Inc sued Taiwan's HTC Corp, which makes touchscreen smartphones using Google software, accusing it of infringing 20 hardware and software patents related to the iPhone.

Even though the suit did not name Google Inc as a defendant, Apple's move was viewed by many analysts as proxy for an attack on the Internet company, whose Nexus One smartphone is manufactured by HTC.
"I think this is kind of an indirect lawsuit against Google," said Kaufman Bros analyst Shaw Wu.
Apple's suit was filed with both the U.S. International Trade Commission and the U.S. District Court in Delaware on Tuesday, and seeks to prohibit HTC from selling, marketing or distributing infringing products in the United States.
The complaint filed with the ITC cited Google's Nexus One, which was launched in January, and other HTC phones such as the Hero, Dream and myTouch -- which run on Google's Android mobile operating system -- as infringing products.
In a statement, a Google spokeswoman said: "We are not a party to this lawsuit. However, we stand behind our Android operating system and the partners who have helped us to develop it."
HTC said in an emailed statement that it was looking at the filings.
"HTC values patent rights and their enforcement but is also committed to defending its own technology innovations," spokesman Keith Nowak said.
Apple's move comes amid fierce competition in the smartphone market, as new players angle for a piece of the fast-growing segment.
Mark Simpson, a patent attorney with law firm Saul Ewing in Philadelphia, said HTC made for an easier target than Google.
"It's probably simpler for them to go after the company making the infringing goods, which is HTC. It's easier to prove at this point," he said.
MKM Partners analyst Tero Kuittinen agreed. "HTC is an optimal target for Apple -- it's a relatively small vendor with a weak brand. It may be easier to push around than Samsung (which also makes Android smartphones). One question here is whether Apple can intimidate operators to back away from new HTC products by flashing the possibility of litigation trouble."

Apple said HTC "knowingly induce(s) users of accused HTC Android products" to infringe on a number of Apple's patents, some dating back to the mid-1990s. They cover user interface processes and other software and hardware components.
"We think competition is healthy, but competitors should create their own original technology, not steal ours," Apple Chief Executive Steve Jobs said in a news release.
An Apple spokesman declined to comment beyond the complaints.
The iPhone held a 14.4 percent smartphone market share in 2009, according to research group Gartner. Phones running Android comprised only 3.9 percent of the market, but were growing fast. Apple lost some share to Android phones in the fourth quarter.
"This move could be a sign Apple is getting rattled by Google's recent momentum in the mobile space -- notably the avalanche of Android products unveiled at Mobile World Congress," said Ben Wood from CCS Insight.
Apple's lawsuit is the latest scrape over ownership of the underlying technology for smartphones -- handsets that play video and music, take pictures and send e-mail.
Eastman Kodak Co in January filed a complaint with the ITC, saying Apple's iPhone and Research in Motion Ltd's BlackBerry camera phones infringe the photography company's patents.
Nokia, the world's top mobile phone maker, has also sued Apple over patents. Apple has countersued.
That dispute, potentially involving hundreds of millions of dollars in annual royalties, reflects the shifting balance of power in the mobile industry as cellphones morph into handheld computers that can play video games and surf the Web.
In its ITC filing against HTC, Apple noted that some of the patents at issue are at the center of its legal fight with Nokia.
Shares of Cupertino, California-based Apple fell 14 cents to close at $208.85 on Nasdaq.

HTC Heroes Apple sued HTC, a Taiwanese manufacturer of mobile phones, on Tuesday, in a lawsuit claiming 20 different patent infringements, largely relating to the user interface of the iPhone, which is manufactured by Apple.

According to the lawsuit, filed with both the United States District Court in Delaware and the  United States International Trade Commission, HTC violated Apple patents pertaining to both multi-touch gestures, which allow users to interact with a device's touchscreen using multiple fingers, as well as patents involving more general touch features.  Devices mentioned in the suit are all phones manufactured by HTC that use Google's Android software.  The lawsuit says that HTC, in selling the phones, knowingly induced those using the mentioned products to violate patents owned by Apple, some of which were filed in the mid-1990s.

Although the lawsuit named only HTC as a defendant, many viewed the action as an indirect challenge to Google, as the lawsuit only covered HTC devices running Google's Android software.  The operating system has seen increasing popularity in the last year, and has increasingly included multi-touch input of the type mentioned in the lawsuit.  

One analyst, from Kaufman Brothers, said, "I think this is kind of an indirect lawsuit against Google."  Others said that Apple was suing HTC instead of Google because the phone manufacturer was an easier target than Google. Another analyst from MKM Partners said that "HTC is an optimal target for Apple-it's a relatively small vendor with a weak brand."

In the documents, Apple said that their goal was to permanently block HTC from importing and selling devices that had the offending qualities, as well a significant cash payment in damages.
