LTO-8 tape media patent lawsuit cripples supply as Sony and Fujifilm face off in court

Case being heard in US, but disties in Middle East, Europe warn delays will go on till at least August

Exclusive A courtroom showdown over a patent infringement allegation that Fujifilm brought against Sony is crippling supply of LTO-8 tape media stateside and further afield, and a resolution doesn't appear to be imminent.

Sony has confirmed to The Register that it is currently not supplying the US market with LTO-8.

The case dates back to 2016 when Fujifilm complained to the United States International Trade Commission (USITC) that Sony was infringing a dozen or so of its tape media patents. The USITC opened investigations and in March last year decided Fujifilm was right and banned Sony from importing tape media, including LTO-7 cartridges, into the USA.

Sony went to the Patent Trial and Appeal Board (PTAB) to counter the Fujifilm accusations and won. Fujifilm then appealed to the US Court of Appeals for the Federal Circuit against the PTAB decision.

In March this year a USITC order (PDF) prevented Fujifilm from importing certain LTO tape cartridges and in May the US Court of Appeals for the Federal Circuit decided Sony was in the right.

The situation hasn't been helped by consolidation and that fact the last people standing are fighting each other in court over IP, with the current ruling meaning only Sony can supply US customers. However, it appears that although Sony is currently ahead (for now), it has decided amid litigation not to supply.

A corporate mouthpiece for Sony confirmed to us: "The US imports of LTO-8 have been stopped at the moment. We refrain from any comments for resuming as we are under dispute."

The company made no further comment on when it expects the conflict to be resolved.

Fujifilm, which manufactures and supplies LTO-7 tape media, told us: "As Fujifilm does not currently manufacture LTO-8 cartridges we can not comment on the availability of this product in the market.

The spokeswoman added, "To date, Fujifilm has not offered LTO8 for sale."

With tape archiving currently under threat from fast access disk vaults and even faster access QLC (4bits/cell) flash down the road, the tape suppliers are doing a damn good job of strangling the tape sector.

The main tape storage media standard employs LTO Ultrium cartridges, with the latest being LTO-8, with 12TB raw capacity. It succeeded the previous LTO-7 with its 6TB raw capacity.

Dan Keldsen, director of customer innovation at object storage maker Wasabi, said LTO-8 tape supply had been patchy in 2019 and is not expected to be resolved sooner than Q3 this year.


Various media suppliers concurred, and some pointed to problems elsewhere too, ImageStore among them:


ImageStore tape shortage statement.

A source in a Middle East distribution business said: "We have been trying for a while to order regular LTO8 tapes but couldn't get any. We have been told there should be tapes around June or July. And we know that it's something which almost every vendor in the market is suffering from - since our customers can't get any tape from anyone else."

According to BackupWorks, IBM has withdrawn from selling LTO-8 tape media because of the lawsuit:


An IBM statement said: "As you know, IBM provides tape libraries, tape subsystems, VTL's and tape mechanisms. But we are not the media manufacturers. To understand this, you will need to talk to those providers." Which means Sony and Fujifilm.

Distributor UK CoolSpirit's website stated:


CoolSpirit told us it may be able to source some IBM LTO-8 media in August, said: "The court case has affected worldwide production." The availability date is currently set for August, it added.

Tape library supplier SpectraLogic refused to comment, despite its Digital Data Storage Outlook 2019 document stating:

"There remain two tape media suppliers. This year a lawsuit between the two drove prices higher on LTO-8 media. Hence, LTO-8 media at 12TB has a higher cost per capacity then LTO-7 at 6TB."

These LTO-8 tape media lawsuits are complicated, with both Sony and Fujifilm trying to either deny individual patent applicability or infringement, and filing multi-hundred page documents with the courts.

For now, ImageStore suggests that unused LTO-7 tape cartridges can be slotted into LTO-8 drives and formatted as M8 tape. It then has a 9TB native capacity compared to the native LTO-7's 6TB capacity. ®

    We're only here for DBIRs

    The cybersecurity landscape continues to expand and evolve rapidly, fueled in large part by the cat-and-mouse game between miscreants trying to get into corporate IT environments and those hired by enterprises and security vendors to keep them out.

    Despite all that, Verizon's annual security breach report is again showing that there are constants in the field, including that ransomware continues to be a fast-growing threat and that the "human element" still plays a central role in most security breaches, whether it's through social engineering, bad decisions, or similar.

    According to the US carrier's 2022 Data Breach Investigations Report (DBIR) released this week [PDF], ransomware accounted for 25 percent of the observed security incidents that occurred between November 1, 2020, and October 31, 2021, and was present in 70 percent of all malware infections. Ransomware outbreaks increased 13 percent year-over-year, a larger increase than the previous five years combined.

    Government departments are guilty of high levels of non-compliance with the UK's off-payroll tax regime, according to a report by MPs.

    Difficulties meeting the IR35 rules, which apply to many IT contractors, in central government reflect poor implementation by Her Majesty's Revenue & Customs (HMRC) and other government bodies, the Public Accounts Committee (PAC) said.

    "Central government is spending hundreds of millions of pounds to cover tax owed for individuals wrongly assessed as self-employed. Government departments and agencies owed, or expected to owe, HMRC £263 million in 2020–21 due to incorrect administration of the rules," the report said.

    Interpol, cops swoop with intel from cybersecurity bods

    Interpol and cops in Africa have arrested a Nigerian man suspected of running a multi-continent cybercrime ring that specialized in phishing emails targeting businesses.

    His alleged operation was responsible for so-called business email compromise (BEC), a mix of fraud and social engineering in which staff at targeted companies are hoodwinked into, for example, wiring funds to scammers or sending out sensitive information. This can be done by sending messages that impersonate executives or suppliers, with instructions on where to send payments or data, sometimes by breaking into an employee's work email account to do so.

    The 37-year-old's detention is part of a year-long, counter-BEC initiative code-named Operation Delilah that involved international law enforcement, and started with intelligence from cybersecurity companies Group-IB, Palo Alto Networks Unit 42, and Trend Micro.
