As long as it conforms to the specifications of JIS/ISO, it can be used freely. ""You don't need permission to use the QR code formulated according to JIS and ISO specifications, and anyone can use it freely. "
Article 22 of the Patent Law stipulates that inventions and utility models granted patent rights shall be novel, creative and practical.
Novelty means that the invention or utility model does not belong to the prior art;
No unit or individual has filed an application for the same invention or utility model with the administrative department for patent in the State Council before the filing date, and it is recorded in the patent application documents published or announced after the filing date.
Creativity means that compared with the prior art, the invention has outstanding substantive features and remarkable progress, and the utility model has substantive features and progress.
Practicality means that the invention or utility model can be manufactured or used and can produce positive effects.
The existing technology mentioned in this law refers to the technology known to the public at home and abroad before the date of application.
Extended data
At present, the application of QR code is basically out of control and disorder.
Nowadays, the use of QR codes is more and more extensive, and more and more mobile phone users have developed the habit of scanning codes at will. However, few people really know what a QR code is.
Simply put, a QR code is a plane figure composed of small black and white squares. After encryption and decryption technology, the simple black-and-white QR code can transmit text and digital information, which is convenient for recording, identification and information interaction. It can hold up to 1850 capital letters or 27 10 numbers or 1 108 bytes, or more than 500 Chinese characters.
According to Juck Zhang, executive director of China QR code standards joint working group and China QR code registration and certification center, the QR code technology is not complicated, and all kinds of QR code "coding systems" are just different in mathematical algorithms, so the technical threshold is not high. Both QR code and bar code can be used as the "ID card" of products to manage and trace items in a unified way.
It is understood that foreign research on two-dimensional code technology began in the late 1980s, and there are more than 250 existing one-dimensional codes and two-dimensional code systems in the world.
At present, the fast response code (QR code) developed by Denso Corporation of Japan in 1994 is widely used in China. Because there was no two-dimensional code technology with independent intellectual property rights in China at that time, two-dimensional code became China's national standard in 2000, which was widely used in government affairs system, intelligent manufacturing, financial payment, e-commerce, news media and other fields, and was closely related to network information security, economic operation environment, social security and people's daily life.
Zhang Yeping said that in order to achieve the goal of market monopoly, QR codes adopted the so-called free market opening strategy, which led to the application of QR codes in China being basically out of control and out of order.
Anyone can download, generate and analyze the QR code through the network, and decode it in real time through the mobile phone at the foreground, but there is no background to identify and monitor the content analyzed at the foreground, so it is often impossible to lock the responsible subject when something goes wrong.
"From malicious advertisements to financial fraud, even sensitive political words, political propaganda, illegal assembly notices, rumors, etc. It can be quickly and widely spread on computer networks and mobile Internet through QR codes. "
