You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 54.163.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 17:28, 10 March 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

==History==
The company was founded in 1987 by [[Tony Chen]] and [[Scott Lin]] and went public on the [[Taiwan Stock Exchange]] on 11 March 2002.<ref name="Company history">((cite web|title=Largan Precision web site, Company History|url=http://www.largan.com.tw/html/about/about_en.asp#02|accessdate=27 February 2013))</ref> 

Scott Lin, one of the co-founders, took the suggestion of his friend Jong Huang, Chairman of Premier Technology, to try to shift the production focus to lighter and thinner lenses instead of glass lenses, which are comparatively heavier and thicker, becoming a significant [[Apple Inc.]] components supplier.<ref name="Taipei Times" /> 

In 2001, the company was certified as compliant with [[ISO 9000|ISO 9001]]. It was merged with Largan Optronic Co., Ltd. A year later, Largan Precision went public on [[Taiwan Stock Exchange]] (TWSE). They developed a projector zoom lens, a VGA lens used in mobile phones, and 3.0 Megapixels 3x zoom digital camera lens. At that time, the company was ranked #2 by profit rate, #92 by net profit after tax, and #141 by revenue growth rate.

As of 2016, Largan Precision is headquartered in Taichung City's Precision Machinery Innovation Technology Park. They have also purchased nearby lands and plan to centralize their production line. 

==Locations==
With the corporate headquarter based in [[Taichung]], [[Taiwan]], Largan currently operates four factories in [[Taiwan]] and two in [[China]].<ref name="Largan CW" />

== Legal dispute ==
In 2013, Largan Precision sued Ability Opto-Electronic Technology Co ([[Chinese language|Chinese]]: 先進光電) for stealing its trade secret. Claimed that four engineers, originally in Largan Precision, started filing patents that infringed on its intellectual property. After more than eight years of litigation, on January 28, 2021, the Intellectual Property Court upheld its first instance judgment, ordering Ability to pay NT$1.52 billion(US$53.72 million) in compensation.<ref>((Cite web|title=「笨到」拿大立光機密申請專利？8年纏訟如何讓先進光變「小立光」｜天下雜誌|url=https://www.cw.com.tw/article/5114372|access-date=2021-09-29|website=天下雜誌|language=zh-Hant-TW))</ref><ref>((Cite web|date=2021-03-06|title=Largan settles IP suit against Ability - Taipei Times|url=https://taipeitimes.com/News/biz/archives/2021/03/06/2003753308|access-date=2021-09-29|website=taipeitimes.com))</ref><ref name=":0">((Cite web|date=2019-10-03|title=Largan files US patent lawsuit against 3 firms - Taipei Times|url=https://www.taipeitimes.com/News/biz/archives/2019/10/03/2003723283|access-date=2021-09-29|website=www.taipeitimes.com))</ref> This set a record of the highest amount of compensation in the history of Taiwan's intellectual property lawsuits. Right after the two companies reached an out-of-court settlement, Largan bought 20 million shares of Ability Optoelectronics Technology Co, giving Largan Precision 15.2 percent of its stock rights.

Over the years, Largan had also sued Newmax Technology Co (Chinese: 新鉅科), [[Samsung Electronics|Samsung Electronics Co]], and [[HP Inc.|HP Inc]] for infringing on four of the company's patents and used it in the production of notebook camera lenses. It is the first time Largan litigated to protect its intellectual property rights for lenses used in notebooks.<ref name=":0" />
